        Response.AppendHeader("Cache-Control", "max-stale=0"); // HTTP 1.1 
        Response.AppendHeader("Cache-Control", "post-check=0"); // HTTP 1.1 
        Response.AppendHeader("Cache-Control", "pre-check=0"); // HTTP 1.1 
        Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.1 
        Response.AppendHeader("Keep-Alive", "timeout=3, max=993"); // HTTP 1.1 
        Response.AppendHeader("Expires", "Mon, 26 Jul 1997 05:00:00 GMT"); // HTTP 1.1

option 2

Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1))
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Response.Cache.SetNoStore()
