ASP.NET Interview Questions and Answers

 

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

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.
