To prevent this u can make the Page_Load event to occur whenever a back button is clicked so that u can make the necessary validations.
U can do this by simply implementing the following piece of code in page_load
Response.Cache.SetCacheability(HttpCacheability.NoCache)
This will make the cache empty and whenever the back button is pressed it fires the Page_Load event.
Try this and let me know whether it works or not

hi
add the following code in each and every page load event
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetAllowResponseInBrowserHistory(false);
or
add the following code in logout page
Response.Write("<script language=javascript>var wnd=window.open('','newWin','height=1,width=1,left=900,top=700,status=no,toolbar=no,menubar=no,scrollbars=no,maximize=false,resizable=1');</script>");
Response.Write("<script language=javascript>wnd.close();</script>");
Response.Write("<script language=javascript>window.open('Login.aspx','_parent',replace=true);</script>");

Well u can use this javascript to solve this problem! Use this javascript on Logout.asp or .aspx page.
<script language="JavaScript">
javascript:window.history.forward(1);
</script>
Whenever user will click Back button , he will be forwarded to logout page again!!

If you disable the cache for all the pages, it will affect the performance of the site considerably. So i always prefer to use javascript instead of setting the cache to NoCache.

x is 1,2...
