<tokenReplayCache>	Registers a token replay cache with a service or a security token handler collection.

Parent Elements

Element	Description
<identityConfiguration>	Specifies service-level identity settings.
<securityTokenHandlerConfiguration>	Provides configuration for a collection of security token handlers.

Remarks

A <caches> element can be specified at the service level under the <identityConfiguration> element or on the security token handler collection level under the <securityTokenHandlerConfiguration> element. Settings on a token handler collection override those specified on the service.

The <caches> element is represented by the IdentityModelCachesElement class. The configured caches are represented by the IdentityModelCaches class.

Example

The following XML shows the configuration of a custom cache for holding session security tokens (SessionSecurityToken). The configuration is taken from the ClaimsAwareWebFarm sample.

<caches>  
  <sessionSecurityTokenCache type="CacheLibrary.SharedSessionSecurityTokenCache, CacheLibrary">  
    <!--cacheServiceAddress points to the centralized session security token cache service running in the web farm.-->  
    <cacheServiceAddress url="http://localhost:4161/SessionSecurityTokenCacheService.svc" />  
  </sessionSecurityTokenCache>  
</caches>
