  This works fine in IE & Firefox for me...
  

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

  I have it in my master page code-behind.

   

  Cheers!

  I have this lines in all my master page code-behind Page_Load method. Now, one interesting observation I have found.

   When a session expires, and I tried to open some page in my application, it redirected me to logout.aspx as it should. After that I clicked on [Back] button of browser for few times. In this case, as the session has expired, I expected logout.aspx rather than the actual pages as they are not cached. But it showed actual page with all the contents.

   

  Any ideas, how can I show logout.aspx page instead of all those pages?

   

  Thanks,

  Ujjaval

  Anyone knows a trick for the Opera browser (well.. at least if you heard of Opera... )

  Thanks! Really helpful. But not working for Safari very weill. Safari will popup window to ask if send back to server, after clicking 'send', you will get the cached page again. Anyone knows how to make it work?

  I have updated the code, the changes were not persisting the way i desired. New code below:

   

   

  Response.ClearHeaders();
              Response.AppendHeader("Cache-Control", "no-cache"); //HTTP 1.1
              Response.AppendHeader("Cache-Control", "private"); // HTTP 1.1
              Response.AppendHeader("Cache-Control", "no-store"); // HTTP 1.1
              Response.AppendHeader("Cache-Control", "must-revalidate"); // HTTP 1.1
              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
