This walkthrough demonstrates how to use the Security Application Block to expire a user token.

To reproduce the demonstration

  1. Authenticate the user. The following code demonstrates how to authenticate a user using the System.Web.Security.Membership class.
  2. IIdentity identity = null;
    if (Membership.ValidateUser("username", "password"))
      identity = new GenericIdentity("username", Membership.Provider.Name);
  3. Create the security cache by adding the following code.
  4. ISecurityCacheProvider secCache = SecurityCacheFactory.GetSecurityCacheProvider("Caching Store Provider");
  5. Call the SaveIdentity method on the security cache object by adding the following code.
  6. IToken token = null; 
    if (identity != null)
      token = secCache.SaveIdentity(identity);
  7. Call the ExpireIdentity method on the security cache object by adding the following code.
  8. secCache.ExpireIdentity(token);

This removes the identity information associated with the token from the cache.
