SamlDoNotCacheCondition Class

Represents a condition that must be taken into account when assessing the validity of a SAML assertion.

Namespace:  System.IdentityModel.Tokens
Assembly:  System.IdentityModel (in System.IdentityModel.dll)

public class SamlDoNotCacheCondition : SamlCondition

SamlSecurityToken security tokens specify their claims using SAML assertions and a set of conditions that must be taken into account when assessing the validity of the SAML assertion. The SamlDoNotCacheCondition class represents one of the conditions defined by the SAML specification and it asserts that the SAML assertion must not be cached. To specify this condition for a SAML assertion, add the SamlDoNotCacheCondition class to the collection returned by the Conditions property.


When the SamlDoNotCacheCondition is added as a condition to a SamlSecurityToken security token that is issued by a security token service for the WCF client, a WCF client does cache the security token. Because the client does not inspect the contents of the issued token, the token is cached. The client is token agnostic for issued tokens type and processes it the returned issued token as an opaque XML element. However, WCF security never caches the received issued token on the service side; it only caches the claims that are extracted from it during the token authentication process.
