Why did you not reply in the topic I gave you this code? Where did you add this code in your page? And do you even understand what it means or didn't you bother to find out?

[mzmishra]

try this
pages.Response.Cache.SetExpires(DateTime.Parse(Dat eTime. Now.ToString()))

Response.Cache.SetCacheability(HttpCacheability.Pr ivate)
Response.Cache.SetNoStore()
Response.AppendHeader("Pragma", "no-cache")

Setting the "cache" meta tag is only a suggestion for web browsers and is not going work all the time.

The only way that I was able to successfully implement such a solution was wrap the page content in an UpdatePanel. When you put your content in an UpdatePanel, everything the user does on the page is done asynchronously. That means when the user hits the back button, the page will appear as if it were the first time loading.
