public void CacheValidationHandler( HttpContext context,
                                    object data,
                                    ref HttpValidationStatus validationStatus )

    else

    }
}


protected void SetCachePolicy( AuthorizationContext filterContext )
 {
     //** IMPORTANT **
     //Since we're performing authorization at the action level, the authorization code runs
     //after the output caching module. In the worst case this could allow an authorized user
     //to cause the page to be cached, then an unauthorized user would later be served the
     //cached page. We work around this by telling proxies not to cache the sensitive page,
     //then we hook our custom authorization code into the caching mechanism so that we have
     //the final say on whether a page should be served from the cache.
     HttpCachePolicyBase cachePolicy = filterContext.HttpContext.Response.Cache;
     cachePolicy.SetProxyMaxAge( new TimeSpan( 0 ) );
     cachePolicy.AddValidationCallback( CacheValidationHandler, null /* data */);
