Reference - Web.config application keys

CMSTrialKey

Contains a temporary trial license key. You can remove this value after installation.

"" (empty string)

CMSHashStringSalt

Sets the salt value that the system uses in hash functions, for example when creating macro signatures. The installer automatically adds the key for new instances of Xperience, with a random GUID as the value.

Note: Changing the hash salt on a website that already has defined content may prevent macros from resolving correctly, or break dialog links and images on your website. If you encounter such problems, you need to re-save the given content or globally re-sign macros (the system then creates the hashes using the new salt).

<add key="CMSHashStringSalt" value="eb2d6fac-8b9e-427c-b98b-3c562dffbb35" />

Random GUID

CMSUseVirtualPathProvider

Indicates if the virtual path provider is enabled in the administration application.

The system uses the virtual path provider to load objects, such as ASCX page layouts, from the database.

<add key="CMSUseVirtualPathProvider" value="false" />

true

CMSClearFieldEditor

Determines behavior when creating new fields for forms in the administration interface. If true, new fields have empty values of attributes. If false, new fields have predefined values, the same as the previously selected field.

<add key="CMSClearFieldEditor" value="false"/>

true

CMSDatabaseCulture

Specifies the default culture of the system’s database.

<add key="CMSDatabaseCulture" value="en-us"/>

Widget configurations are only stored in the Temp_PageBuilderWidgets table temporarily before they are saved and transferred to the CMS_Document table. However, they may remain stored in the temporary table if an error occurs while using the page builder. The value is in hours.

<add key="CMSDeleteTempPageBuilderWidgetsOlderThan" value="5"/>

1

CMSMVCResolveRelativeUrls

Note: This key must be added to the web.config (MVC5 projects) or appsettings.json (ASP.NET Core projects) file of your live site application.

The system provides an output filter that automatically resolves all virtual relative URLs (~/<link path>) on the side of the MVC live site (based on the environment where the site is actually running). This filter prevents content editors from creating invalid links in cases where your MVC application does not resolve URLs (by processing the content using the Html.Kentico().ResolveUrls method).

If you wish to disable the output filter and resolve URLs manually in your code, set the key to false.

<add key="CMSMVCResolveRelativeUrls" value="false"/>

You will typically use this if you are using a custom authentication provider whose authentication type is a non-standard one (e.g. Federated authentication) to make the system handle it as if it were Windows or Forms authentication.

The following values are available:

• default: standard behavior
• forms: IsFormsAuthentication always returns true, IsWindowsAuthentication always returns false
• windows: IsFormsAuthentication always returns false, IsWindowsAuthentication always returns true
• both: IsFormsAuthentication always returns true, IsWindowsAuthentication always returns true

<add key="CMSAuthenticationType" value="windows" />

true

CMSSelectorMaxDisplayedItems

Sets the maximum amount of items displayed in drop‑down list selectors in the administration interface when the number of selectable objects is higher than the value of the CMSSelectorMaxDisplayedTotalItems key. Users can select the remaining objects in a dialog that can be opened through the (more items…) option.

The value of this key can be overridden for individual UniSelector controls.

<add key="CMSSelectorMaxDisplayedItems" value="20" />

25

CMSSelectorMaxDisplayedTotalItems

Limits the maximum number of items displayed in drop‑down list selectors in the administration interface. If there are more selectable objects, the list is shortened (to the number specified by the CMSSelectorMaxDisplayedItems key) and the (more items…) option is added.

The value of this key can be overridden for individual UniSelector controls.

<add key="CMSSelectorMaxDisplayedTotalItems" value="30" />

50

CMSWebAnalyticsShowFullData

By default, the system reduces the density of data displayed in analytics report graphs (to improve performance and graph load times for graphs with a very large volume of data). Set the CMSWebAnalyticsShowFullData key to true to have report graphs display full data.

<add key="CMSWebAnalyticsShowFullData" value="true"/>

false

CMSPhysicalFilesCacheMinutes

Sets the number of minutes for which clients consider physical files to be valid and up-to-date when using client caching (i.e. the length of the client cache expiration time for files). Specifically, the key determines how the server sets the Expires response header for file requests.

The key only applies to files stored on the file system that are served using the GetResource.ashx handler. Other types of dynamic files use the expiration time set in Settings -> System -> Performance -> Client cache (minutes) within the administration interface. Physical files that are requested directly use the IIS client cache configuration.

See also: Caching files and resources

<add key="CMSPhysicalFilesCacheMinutes" value="60"/>

<add key="CMSUrlHost" value="my.proxyserver.com" />

""

CMSUrlPort

Specifies the port number used in certain types of URLs (for example GetResource requests for images or modal dialog URLs). Standard navigation URLs of web pages are not affected.

If not set, the URL port is automatically taken from the current request (80 in most cases).

Add this key if you wish to generate URLs with a specific port number, regardless of the port supplied in requests.

The CMSUrlPort key may also be useful in scenarios where requests are redirected to a non‑standard port number, but you wish to use the usual HTTP port in URLs (for example in a web farm environment, with a load balancer directing traffic to multiple servers identified by different port numbers).

CMSImportWindowsRoles

When Windows authentication is used and this key set to true, the domain groups of users in Active Directory are imported into the system as roles.

<add key="CMSImportWindowsRoles" value="false"/>

true

CMSRoleImportFormat

When mixed-mode authentication is used, this key determines the format of role names which are imported from Active Directory:

• SAM – the format of imported roles is rolename.
• DomainSAM – the format of imported roles is domain-rolename.

<add key="CMSRoleImportFormat" value="DomainSAM"/>

DomainSAM

CMSEnsureSafeUserNames

Indicates if the system replaces forbidden characters in user names imported from Active Directory.

If the key is false, the system also uses less restrictive validation of users names for standard users (applies when new users register, or when creating or editing users in the administration interface). See the CMSUserValidationRegEx key for details.

<add key="CMSEnsureSafeUserNames" value="false" />

true

CMSEnsureSafeRoleNames

Indicates if the system replaces forbidden characters in the code names of roles imported from Active Directory.

If the key is false, you may experience problems with roles names containing certain forbidden characters, for example with leading underscores characters ( _ ). Therefore, it is NOT RECOMMENDED to set the key to false.

<add key="CMSEnsureSafeRoleNames" value="false" />

true

CMSForbiddenUserNameCharactersReplacement

Sets the character that replaces forbidden characters in user names imported from Active Directory.

If not set, the value from Settings -> URLs and SEO -> Forbidden characters replacement is used.

<add key="CMSForbiddenUserNameCharactersReplacement" value="-" />

CMSForbiddenRoleNameCharactersReplacement

Sets the character that replaces forbidden characters in role names imported from Active Directory.

If not set, the value from Settings -> URLs and SEO -> Forbidden characters replacement is used.

<add key="CMSForbiddenRoleNameCharactersReplacement" value="-" />

CMSUserValidationRegEx

<add key="CMSUserValidationRegEx" value="([A-Za-z0-9-]+)" />

CMSForbiddenURLValues

The characters entered as the value of this key are forbidden in URL paths and will be replaced automatically by the character specified in the Forbidden characters replacement setting in Settings -> URLs and SEO.

By default, the following characters are forbidden:

\/:*?"<>|&%.’#[]+=„“ and the space character.

If you add this key to the web.config, its value will override the default forbidden character set. This way, you can either allow some of the forbidden characters or add new ones.

Please note that it is recommended to keep the default characters forbidden, since they may prevent certain types of URLs from working correctly if entered into URL paths.

Also, keep in mind that some characters need to be escaped in the web.config according to standard XML rules, e.g. enter < instead of the < character.

<add key="CMSForbiddenURLValues" value="\/:$?&quot;&lt;&gt;|&amp;%.&apos;#[] =" />

CMSLimitUrlReplacements

While enabled, consecutive forbidden characters in URLs will be replaced by only a single replacement character and forbidden URL characters located at the beginning or end of the path will be removed completely instead of being replaced. If set to false, each forbidden character is replaced individually.

<add key="CMSLimitUrlReplacements" value="false" />

true

CMSStagingAcceptAllCertificates

If set to true, the system accepts all certificates when performing content staging tasks over a secured protocol (HTTPS). Includes self-signed certificates. If false, the system only accepts certificates generated by a trusted certification authority.

<add key="CMSStagingAcceptAllCertificates" value="true" />

false

CMSMediaFileMaxStagingSize

Sets the maximum size of media library files that are synchronized via staging (in kiloBytes). Add the key to the web.config file of projects that work as source servers in your staging environment.

The system does not synchronize binary data for media library files above the limit. Synchronization tasks for such files only transfer the database definitions of the media objects, without the actual files.

<add key="CMSMediaFileMaxStagingSize" value="1024" />

2147483647 (int.MaxValue)

CMSStagingTreatServerNamesAsInstances

On Xperience instances that contain multiple sites and use staging, changes made to global objects produce staging tasks for all staging servers across all sites. If you synchronize such tasks at different times on different sites, you risk overwriting newer data with the data of old synchronization tasks (we recommend synchronizing such changes at the same time on all servers and sites).

If you have full control over all sites on your instance, you can define the same set of target servers for each site (each server must have an identical Code name across all sites), and set the CMSStagingTreatServerNamesAsInstances key to true. When a global staging task is synchronized, the system then automatically deletes the task from servers with matching code names on the other sites.

The default value is false because code name collisions may occur for staging servers on unrelated sites.

<add key="CMSStagingTreatServerNamesAsInstances" value="true" />

false

CMSStagingServerName

Name of the staging server used for advanced bi-directional content staging. The value needs to be used as the code name when defining this server as a target server of other servers.

See Bi-directional content staging for more information.

<add key="CMSStagingServerName" value="server2" />

"" (empty string)

CMSStagingServiceTimeout

Sets timeout interval for the service used to synchronize staging tasks. The key must be configured within the web.config file on the source instance from which the tasks are being synchronized.

If true, tasks for global objects are logged only for the sites to which the respective objects are assigned.

<add key="CMSStagingLogGlobalObjectsOnlyForAssignedSites" value="true" />

false

CMSStagingUseAutomaticOrdering

Determines whether the system applies automatic ordering to pages created via staging. If true (by default), the system overrides the ordering of new pages according to the Content -> Content management -> New page ordering setting.

Configure this web.config key on target servers that process incoming staging tasks.

<add key="CMSStagingUseAutomaticOrdering" value="false" />

true

CMSCIEncoding

Sets the character encoding used when the continuous integration solution generates non-binary files in the project’s CIRepository folder. The key supports values matching the encoding names listed in the Encoding Class article.

Changing the value of the CMSCIEncoding key does not update the encoding type of existing files in the CIRepository folder. To fully update the encoding of the repository content, you need to:

• Run complete serialization for all objects.
• Manually update the encoding type of your repository.config file.

<add key="CMSCIEncoding" value="utf-16" />

utf-8

CMSCIRepositoryPath

Sets the location of the continuous integration file repository root folder. The key’s value must be an absolute or relative path of a folder on a local drive, or a network location for which the application has sufficient permissions.

The specified location is used when serializing object data to the file system and when restoring data back to the database. The key also allows you to set a shared continuous integration repository:

• Using a shared repository is strongly recommended for live site and administration projects that manage the same site.
• You can set a shared repository when developing multiple projects with the same database.

<add key="CMSCIRepositoryPath" value="C:\ExternalSourceControl\CIRepository" />

App_Data\CIRepository

All languages are enabled by default.

<add key="CMSEnableSyntaxHighlighting.CSS" value="false" />

true

CMSShowLineNumbers

Determines whether the code editor in the administration interface displays the panel containing line numbers by default.

Note: The editor fields used in the administration interface always have line numbers disabled by default. The key only affects custom fields that have displaying of line numbers enabled (fields using the Macro editor form control with the Show line numbers parameter enabled).

<add key="CMSShowLineNumbers" value="false" />

true

CMSUseStrictInventoryManagement

Products that use inventory tracking and have the Sell only if items available property enabled may be sold even when the inventory is depleted in cases where multiple customers place orders concurrently. By default, the system logs a warning into the event log if such a situation occurs.

If you set the key to true, the system throws an InvalidOperationException when a customer attempts to create an order containing a product that became out-of-stock due to another concurrently placed order.

If you wish to enable the CMSUseStrictInventoryManagement key, you need to manually ensure that your custom code handles the exception and displays appropriate information to customers.

<add key="CMSUseStrictInventoryManagement" value="true"/>

false

CMSEmailTransferEncoding

Specifies the type of transfer encoding used for emails sent from Xperience.

Supported values are: base64, quotedprintable, sevenbit

<add key="CMSEmailTransferEncoding" value="QuotedPrintable" />

The CMSEmailDeleteBatchSize key sets the batch size for the number of emails deleted within a single database operation. The default value is 2000.

You can set a different value if you encounter related database performance issues or timeout errors. For example if you have a database server with relatively low performance and your instance contains a very large number of sent and archived emails.

<add key="CMSEmailDeleteBatchSize" value="200" />

2000

CMSEmailSendLimit

Sets the maximum number of messages sent to individual SMTP servers in a single connection. When the limit is reached, the connection is automatically closed and a new one opens. The process continues until all messages are sent.

You can lower the value if you encounter SMTP errors with too many messages set per connection.

<add key="CMSEmailSendLimit" value="20" />

50

CMSLogEmails

Enables logging of all sent emails to the ~/App_Data/logemails.log file.

The log contains each email’s timestamp, recipients, sender, subject, and custom headers and their encoding (UTF-8 by default).

<add key="CMSLogEmails" value="true"/>

Depends on debugging settings

 CMSDebugEmails

Disables sending of emails to the actual recipients. The system only logs emails into the event log. Helpful if you need to test the functionality, but do not want the emails to actually reach the recipients.

• To view the event log, open the Event log application.
• The emails are logged as Information type events.
• The Event code column contains the recipient’s address.
• The system randomly generates Sending failed for <recipient’s email address> errors to simulate sending errors.

<add key="CMSDebugEmails" value="true"/>

false

CMSEmailUtmParametersForAllLinks

If true, UTM parameters are added into all links in marketing emails, including external links. As opposed to the default behavior with enabled UTM tracking, when only relative  email links (relative to your current site) are tagged by the specified UTM parameters.

• physical disk path - e.g. c:\myfiles\mysite
• virtual path - e.g. ~/UploadedFiles
• UNC path - e.g. \\server\folder

<add key="CMSSiteUtilsFolderPath" value="\\server\MyCustomFolder" />

CMSDefaultListingFilterLimit

Determines the minimum number of items that must be included in a listing in order for a filter to be shown. If the number of listed items is lower than this value, the filter is not displayed. If it is larger, the filter is displayed. This applies to all listings (UniGrid controls) across the entire UI.

<add key="CMSDefaultListingFilterLimit" value="40" />

25

CMSDefaultPageSizeOptions

Sets the options available in the page size selector for listings in the administration interface (the Items per page setting). Values must be separated by commas.

You can use the ##ALL## value to add an option that lists all available rows on a single page (not recommended if you have objects with a very large number of records).

<add key="CMSDefaultPageSizeOptions" value="10,50,200" />

5,10,25,50,100

CMSDefaultListingPageSize

Sets the initial page size of listings in the administration interface (the Items per page setting). If the value is not included among the options defined by the CMSDefaultPageSizeOptions key, the system automatically inserts the value as an additional option.

<add key="CMSDefaultListingPageSize" value="50" />

25

CMSListingShowFirstLastButtons

If true, the first and last page link buttons are included in the pagers of listings in the administration interface (with a large enough number of items). If false, the buttons are always hidden.

<add key="CMSListingShowFirstLastButtons" value="true" />

false

CMSListingShowDirectPageControl

If true, a text box that allows the current page to be changed by directly entering a number is included in pagers of listings in the administration interface (with a large enough number of items). If false, the control is always hidden.

<add key="CMSListingShowDirectPageControl" value="false" />

true

CMSUseAutomaticScheduler

By default, the system uses automatic scheduling – the scheduler periodically requests the ~/CMSPages/Scheduler.ashx route, which ensures that scheduled tasks are processed regularly even if there is no website activity.

Can be set to false for the Xperience administration application, which causes scheduled tasks to be processed at the end of every request sent to the administration. This means that tasks are only executed when user activity in the administration generates requests.

The request-based scheduler is not available for the live site. On the side of the live site application, setting the key to false disables the scheduler.

For more information, see Configuring scheduled task execution.

<add key="CMSUseAutomaticScheduler" value="false" />

true

CMSSchedulerAcceptAllCertificates

If true, all security certificates (including invalid ones) will be accepted when accessing the ~/CMSPages/Scheduler.ashx route via a secured protocol.

<add key="CMSSchedulerAcceptAllCertificates" value="true" />

false

CMSSchedulerUserName

Sets the user name under which the ~/CMSPages/Scheduler.ashx route is accessed (e.g. when using windows authentication).

<add key="CMSSchedulerUserName" value="office\myname" />

"" (blank username)

CMSSchedulerPassword

Sets the password for the user name under which the ~/CMSPages/Scheduler.ashx route is accessed.

<add key="CMSSchedulerPassword" value="mypassword123" />

Supply the full URL of the live site application in the format: <scheme><domain><port><virtual directory>

Add this key to the web.config or appsettings.json files of both the administration and live site projects:

<add key="CMSSchedulerPresentationUrl" value="http://localhost:5000" />

"CMSSchedulerPresentationUrl": "http://localhost:5000",

"" (empty string)

CMSProcessContactActionsInterval

Sets the interval (in seconds) in which contact activities are batch processed by the system. Consider raising the interval if your system processes a large number of activities.

You can configure the processing interval separately for the administration and live site applications. Adding the key to the live site application affects the interval at which logged activities and contact detail updates are saved from the memory into the database. Adding the key to the administration application affects how often the system recalculates the data that could be affected by activities and contact updates.

<add key="CMSProcessContactActionsInterval" value="30" />

10

CMSCreateContactActionsLogWorker

If enabled, all administration web farm servers recalculate contact scores, contact groups, personas, and marketing automation triggers.

If you wish to improve performance, you can set this key to false for one or more of your web farm servers, and the recalculation will be disabled for them.

Note: If you set the key value to false for all of your web farm servers, the recalculation will be disabled completely.

<add key="CMSCreateContactActionsLogWorker" value="false"/>

true

CMSGeoIPLocationFileName

Sets the name of the database file used by the geolocation feature for contacts. The file must be placed in the ~/App_Data/CMSModules/WebAnalytics/MaxMind/ folder of your project.

<add key="CMSGeoIPLocationFileName" value="GeoIP2-City.mmdb" />

GeoLite2-City.mmdb

CMSSalesForceUseSandbox

Note: This key is an experimental feature, and may not work in all possible Salesforce integration scenarios.

Allows you to set up and test the Salesforce integration on a Sandbox organization instead of a production org. Add the key to the web.config file of your administration project.

The key ensures that the system connects to Salesforce using the https://test.salesforce.com domain.

Once you are ready to connect to your production organization, remove the key or set its value to false, and re-authorize access to Salesforce.

<add key="CMSSalesForceUseSandbox" value="true" /> 

false

CMSAcceptAllCertificates

Indicates whether application requests should accept all certificates (including invalid certificates). This key ensures the same as if the following keys were enabled at the same time:

• CMSSearchCrawlerAcceptAllCertificates
• CMSSchedulerAcceptAllCertificates
• CMSStagingAcceptAllCertificates
• CMSValidationAcceptAllCertificates

<add key="CMSAcceptAllCertificates" value="true"/>

false

CMSAdminEmergencyReset

Allows you to recover access to the administration interface if you forget the password of your administrator account. The value must consist of the following parts, separated by semicolons:

• Username of the account
• New password for the account
• Optional true/false value which specifies whether you want to create a new user with the Global administrator privilege level.

The system automatically deletes the key after you gain access to the administration interface.

See also: Configuring password resets for Xperience administration

<add key="CMSAdminEmergencyReset" value="admin;password;true" />

CMSAllowOnlySimpleMacros

If true, only simple macros (i.e. those which do not need a security check) are allowed. All others will not be resolved. If true, the CMSTextBox control does not add security signatures to macros in the administration interface.

<add key="CMSAllowOnlySimpleMacros" value="true"/>

false

CMSEnableClickjackingProtection

Note: This key must be added to the web.config (MVC5 projects) or appsettings.json (ASP.NET Core projects) file of your live site application.

When set to false, the key disables the Content Security Policy (CSP) headers that specify the frame-ancestors policy for the HTTP responses of preview mode requests. Only disable the key if you want to configure adding of CSP headers on your own (otherwise preview URLs would be susceptible to clickjacking attacks).

See also: Adding preview mode support

<add key="CMSEnableClickjackingProtection" value="false"/>

true

CMSEnableCsrfProtection

Indicates whether the system uses security tokens to protect the Xperience administration application against Cross site request forgery attacks. Only set this key to false if you have a custom security mechanism against CSRF.

<add key="CMSEnableCsrfProtection" value="false" />

true

CMSEnableWIF

Overwrites the setting of the Enable WIF authentication option in Settings -> Security & Membership -> Authentication -> Claims-based authentication.

If included in the web.config file and set to false, this key can override enabled WIF authentication in case you have not established an administrator account (as described in Claims-based authentication) and you do not have access to the administration interface.

<add key="CMSEnableWIF" value="false"/>

CMSPasswordSalt

The password salt is a string that is appended to user passwords before they are hashed (to improve security). By default, the salt contains the randomly generated GUID of the given user. The content of this key is added after the base salt value to further increase the length of the salt.

Only applies if the application stores passwords using the SHA2 with salt format, which you can configure in Settings -> Membership & Security -> Passwords -> Password format.

See also: Setting the user password format

<add key="CMSPasswordSalt" value="SaltText" />

CMSRenewSessionAuthChange

When set to true, the system enforces a change of the session ID when a user signs in or out of the Xperience administration interface (does not apply to the live site). Provides protection against session fixation attacks.

If you enable this key, users cannot preserve their session data after signing in or out.

See also: Session protection

<add key="CMSRenewSessionAuthChange" value="true" />

false

CMSValidationAcceptAllCertificates

If set to true, the system accepts all certificates when validating website code or accessibility (e.g. CSS validation) using a 3rd party validation service over a secured protocol (HTTPS). This includes self-signed certificates. If false, the system only accepts certificates generated by a trusted certification authority.

<add key="CMSValidationAcceptAllCertificates" value="true"/>

false

CMSBizFormMailEncodeFields

Visitors can potentially submit forms containing malicious HTML values. By default, form notification and autoresponder emails do not encode displayed field values. This can lead to potential HTML injection if the recipient’s email client is configured to display HTML content.

If the CMSBizFormMailEncodeFields key is set to true, autoresponder and notification emails encode the values of the submitted form’s fields. Add the key to both your live site and administration projects.

<add key="CMSBizFormMailEncodeFields" value="true"/>

false

CMSSearchIndexPath

Sets the path of a custom directory where the system stores smart search index files (only applies to local search indexes).

<add key="CMSSearchIndexPath" value="App_Data\MyCustomIndexes" />

CMSProcessSearchTasksByScheduler

By default, the smart search creates and runs local indexing tasks immediately whenever content covered by a search index is created or modified.

If you set this key to true, the system does NOT run indexing tasks upon creation – they need to be processed periodically, typically using the Execute local search tasks scheduled task.

Note: The key does not affect processing of tasks for Azure search indexes. Azure search tasks are always processed by the Execute Azure search tasks scheduled task.

<add key="CMSProcessSearchTasksByScheduler" value="true" />

false

CMSCrawlerAllowSiteAliasRedirect

When Pages search indexes process the HTML output of pages, the crawler by default reads pages in scenarios where a custom redirect switches from the domain in the site’s main presentation URL to a live site domain alias. Setting this key to false only allows indexing if the page is running on its main live site URL (the domain may be different between culture versions of pages).

<add key="CMSCrawlerAllowSiteAliasRedirect" value="false" />

true

CMSSearchCrawlerAcceptAllCertificates

When Pages search indexes process the HTML output of pages, the crawler by default does not cover pages on sites using a secured protocol (HTTPS) without a certificate from a trusted authority. For example, you may encounter the problem in development environments that use a self-signed certificate.

If you set this key to true, the system accepts all certificates.

Note: Setting the CMSSearchCrawlerAcceptAllCertificates key to true poses a security vulnerability and should not be used in production environments.

<add key="CMSSearchCrawlerAcceptAllCertificates" value="true" />

false

CMSSearchMaxFieldLength

Sets the maximum number of terms that the smart search allows in a single index field.

<add key="CMSSearchMaxFieldLength" value="10000" />

Unlimited

CMSSearchMaxResultsNumber

Sets the maximum number of results that the smart search can return for a single search request, when using local search indexes. If a search produces more matching results, the system ignores the items that do not fit into the limit.

The purpose of the limit is to avoid processing of large numbers of search results with low relevance. If you use very large search indexes that regularly produce more than 1000 results (the default limit), you can either increase the value or set up search filters to help narrow down the search.

Important: The key may not apply, depending on your search implementation. The maximum number of search results is overriden by the NumberOfProcessedResults property of the SearchParameters object that you use to perform the search. If you create the search parameters using the SearchParameters.PrepareForPages method, the default number of processed results is 100.

<add key="CMSSearchMaxResultsNumber" value="3000" />

1000

CMSSearchSynonymsWeight

Sets the relevance (result score) that the search assigns to items found through the synonym search (i.e. when using Any word or synonyms search mode).

The key’s value must be a decimal number ranging from 0 to 1. A larger number assigns higher relevance to synonyms. If you set 1, the score of synonyms is equal to words in the original unexpanded search expression.

Only applies when using local search indexes.

<add key="CMSSearchSynonymsWeight" value="0.8" />

0.9

CMSSmartSearchLockPollInterval

Specifies how often (time in milliseconds) the smart search indexer attempts to acquire a lock on index files (for local indexes).

The default value of this key is 500 milliseconds.

Set a lower value if the following exception is being logged in your Event log.

Lock obtain timed out: CMS.SiteProvider.SearchLock

<add key="CMSSmartSearchLockPollInterval" value="300" />

500 ms

CMSSmartSearchLockTimeout

Defines the timeout period (in milliseconds) during which the smart search indexer attempts to acquire a lock on index files (for local indexes).

The default value of this key is 1000 milliseconds.

<add key="CMSSmartSearchLockTimeout" value="1500" />

1000 ms

CMSSubsetAnalyzerWordRegex

Sets a regular expression that determines which characters are allowed in the “words” processed by local search indexes with Subset and Starts with analyzers.

The analyzers use the following steps to create search tokens:

1. Divide text into words
2. Tokenize the substrings inside the words (according to the analyzer type)

The words created in the first step may contain only characters that match the regular expression in the key’s value. Any other characters split the text into separate words.

By default, the following characters are allowed:

• word characters (upper and lower case letters, numbers, underscores)
• at symbols (@)
• periods ( . )

<add key="CMSSubsetAnalyzerWordRegex" value="(\w|@|\.|\$)+" />

(\w|@|\.)+

CMSSearchStoreContentField

Determines whether the smart search stores the original untokenized Content field within index files.

Warning: Setting the key to true reduces indexing performance and increases the size of index files (the difference can be GBs of data for very large indexes). Only enable the key if you need to inspect or debug the content of your index files on development sites. Never enable the key on production sites.

<add key="CMSSearchStoreContentField" value="true" />

false

CMSAzureSearchDnsSuffix

Modifies the domain suffix appended by the system to requests sent to Azure Cognitive Search.

By default, the system assumes Azure Search services are hosted on the search.windows.net domain. This key overrides the default behavior, allowing you to specify a custom domain suffix. This can be useful, for example, when running search services on Azure Government subscriptions, which are hosted with the search.azure.us domain suffix.

<add key="CMSAzureSearchDnsSuffix" value="search.azure.us" />

search.windows.net

CMSSearchDetectTextEncoding

Indicates whether the attachment search uses automatic detection of character encoding for text files (txt and csv).

By default, the search can read text files that use the following encoding:

• UTF-8
• The default Windows encoding (the operating system’s current ANSI code page)

If you enable automatic detection, the system attempts to detect the encoding type for each file, and use the correct option when reading the content.

Note: Correct encoding detection is not guaranteed for all files. Automatic detection also slightly increases the time required to index text files.

<add key="CMSSearchDetectTextEncoding" value="true" />

false

CMSSearchIndexXmlAttributes

Determines whether the attachment search includes the values of tag attributes when indexing XML files.

<add key="CMSSearchIndexXmlAttributes" value="true" />

 false

CMSSearchIndexXmlComments

Determines whether the attachment search includes comments when indexing XML files.

<add key="CMSSearchIndexXmlComments" value="true" />

 false

CMSSearchMaxAttachmentSize

Sets the maximum allowed file size in kB for the attachment search. The search ignores page attachments whose size exceeds the value.

Indexing very large files can be resource intensive and have a negative impact on your website’s performance.

<add key="CMSSearchMaxAttachmentSize" value="10000" />

0 (unlimited)

CMSTranslationServicesUseCDATAForTransUnit

Use if you want to export XLIFF files without CDATA notation.

<add key="CMSTranslationServicesUseCDATAForTransUnit" value="false" />

true

CMSDefaultSpellCheckerCulture

Specifies the default culture of the built-in spell-checker for the rich text field editor. This culture is used when the dictionary for the currently selected content culture is not found.

<add key="CMSDefaultSpellCheckerCulture" value="en-US" />

en-us

CMSShowLogonCultureSelector

Indicates if the administration interface sign-in page displays a drop-down list with available user interface languages.

<add key="CMSShowLogonCultureSelector" value="false" />

true

CMSDefaultUICulture

Specifies the default UI culture.

If you use this key, you also need to:

1. Add a corresponding resource string file (localization pack) into the ~\CMSResources folder.
2. Rename the default CMS.resx file to CMS.en-us.resx.
3. Rename the new culture’s resource string file to CMS.resx.

This is needed because the CMS.resx file is used when the (default) option is selected as a user’s Preferred user interface culture.

<add key="CMSDefaultUICulture" value="en-nz"/>

en-us

CMSUseSQLResourceManagerAsPrimary

Changes the priority of used localization resource strings to:

1. custom.resx
2. cms.resx
3. database (Xperience administration -> Localization application)

<add key="CMSUseSQLResourceManagerAsPrimary" value="false" />

true

CMSWebAnalyticsProcessingInterval

Sets the interval (in seconds) between batch processing operations that save web analytics data from the application memory to the database. You can set a different interval if you wish to optimize your site’s memory or database performance.

Web analytics logging occurs on the live site, so you need to add the key to the web.config (MVC5 projects) or appsettings.json (ASP.NET Core projects) file of your live site application.

<add key="CMSWebAnalyticsProcessingInterval" value="30" />

10

CMSWebFarmMode

Note: The purpose of this key is only for backwards compatibility and other special scenarios. Instead, set the web farm mode using the Settings -> Versioning & Synchronization -> Web farm -> Web farm mode setting in the Xperience administration interface.

Indicates if web farms are:

• disabled
• automatic – no further configuration is needed.
• manual – requires manual configuration of web farm servers in the system.

<add key="CMSWebFarmMode" value="automatic"/>

disabled

CMSInstanceNameSuffix

When using Automatic web farm mode, the system generates the names of servers by combining the machine name and virtual directory in which the application is running. You can use this key to set an additional suffix that is added to the automatic server name for the given instance.

If you do not set a custom value, the system automatically uses the AutoExternalWeb suffix for external web applications running the Xperience API (typically live site applications).

"" (empty string)
– or –
AutoExternalWeb

CMSWebFarmServerName

Code name of the web farm server. This value is used for manual web farm synchronization support.

This setting overrides the name assigned by the system in Automatic web farm mode.

<add key="CMSWebFarmServerName" value="server1" />

"" (empty string)

CMSWebFarmSyncInterval

Average time before a created web farm synchronization task is processed by web farm servers (the maximum possible time before a task is processed is double of the specified interval).

<add key="CMSWebFarmSyncInterval" value="100" />

2000 ms

CMSWebFarmNotRespondingInterval

By default, web farm servers that transition to the Not responding status remain in the system for 24 hours. The key can be used to change the interval to a specified number of minutes, e.g., 60 for 1 hour.

The web farm continues to generate synchronization tasks for Not responding servers, which can cause unnecessary load and performance problems. You can set the interval to a lower value if you encounter such problems, particularly in hosting environments that dynamically adjust the number of instances (e.g., autoscaling in Azure App Services).

In Automatic web farm mode, servers are deleted after the interval passes. In Manual web farm mode, the servers remain, but the system stops generating memory synchronization tasks (other task types are still generated).

<add key="CMSWebFarmNotRespondingInterval" value="60" />

1440
(24 hours)

CMSWebFarmMaxFileSize

If the CMSWebFarmSynchronizeFiles key is enabled, you can limit the maximum size of synchronized files using this key. The value is entered in kiloBytes and files larger than this value will not be synchronized.

<add key="CMSWebFarmMaxFileSize" value="1024" />

2147483647 (int.MaxValue)

CMSWebFarmApplicationPhysicalPath

Path to the application on the disk used for synchronizing physical files.

<add key="CMSWebFarmApplicationPhysicalPath" value="C:\inetpub\wwwroot\Xperience" />

CMSWebFarmSynchronizeFiles

Determines if web farms synchronize files in general. This key enables synchronization of:

• Attachments
• Meta files
• Media files
• Form files
• Avatars

Microsoft Azure notes:

For projects hosted in Microsoft Azure Web Apps, we strongly recommend that you manually set the key to false. Otherwise, you may encounter file system collisions when scaling to multiple instances.

<add key="CMSWebFarmSynchronizeFiles" value="false" />

<add key="CMSWebFarmSynchronizeDeleteFiles" value="true" />

true

CMSWebFarmTaskDeleteBatchSize

The system regularly performs cleanup of unnecessary web farm synchronization tasks (orphaned tasks without a related web farm server, etc.). The key sets the batch size for the number of tasks deleted within a single database operation. The default value is 500.

You can set a different value if you encounter related database timeout errors, for example if you have a database server with relatively low performance and your instance contains large synchronization tasks with binary data.

<add key="CMSWebFarmTaskDeleteBatchSize" value="100" />

500

CMSAzureAccountName

Specifies the name of the Azure Storage account that the application will use for its file system.

If you wish to run the application on the local emulator, enter devstoreaccount1 as the value.

<add key="CMSAzureAccountName" value="devstoreaccount1"/>

CMSAzureSharedKey

Contains the primary access key for the storage account specified in the CMSAzureAccountName setting.

You can find the appropriate value for your storage account on the Microsoft Azure Management Portal.

<add key="CMSAzureSharedKey" value="Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw=="/>

CMSAzureRootContainer

Specifies the name of the blob container that will serve as the root of the application’s file system on the Azure storage account.

This can be useful in scenarios where multiple applications use the same storage account.

The default value is cmsstorage.

<add key="CMSAzureRootContainer" value="CustomRoot"/>

CMSAzurePublicContainer

Indicates if the blob container used to store the applications file system should be public. If set to true, it will be possible to access files directly through the URL of the appropriate blob service, for example:

<StorageAccountName>.blob.core.windows.net/cmsroot/corporatesite/media/imagelibrary/logo.png

<add key="CMSAzurePublicContainer" value="true"/>

CMSAzureStorageCacheCleanerThreshold

Specifies a threshold in gigabytes that is used by the Clean Azure storage cache scheduled task. When the threshold is exceeded and the scheduled task is enabled, the system starts to delete files in the Azure Cache and Azure Temp folders from the oldest to the newest.

The default value is 45GB.

<add key="CMSAzureStorageCacheCleanerThreshold" value="45"/>

CMSAzureStorageCacheCleanerKeepLimit

Specifies an amount in gigabytes that is used by the Clean Azure storage cache scheduled task. The amount is the target size of the Azure Cache and Azure Temp folders when the scheduled task deletes the files.

The size of the excluded paths (set by the CMSAzureStorageCacheCleanerExcludedPaths web.config key) is included in the amount.

The default value is 10GB.
