Is it possible to prevent a browser from caching an ASPX page?

 Posted by Poster on 7/1/2008 | Category: ASP.NET Interview questions | Views: 5552

Just call SetNoStore on the HttpCachePolicy object exposed through the Response object's Cache property, as demonstrated here:

        <%@ Page Language="C#" %>

Response.Cache.SetNoStore ();
Response.Write (DateTime.Now.ToLongTimeString ());

SetNoStore works by returning a Cache-Control: private, no-store header in the HTTP response. In this example, it prevents caching of a Web page that shows the current time.
