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 http://himabinduvejella.blogspot.com http://sysntaxhelp.com/asp.net http://groups.google.com/group/mugh Hima's Tech Blog

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>");

Hi, Use Session.Abandon() Session.Clear() FormsAuthentication.SignOut() Response.Redirect("~/Default.aspx?signout=1") in the signout button and login use FormsAuthentication.loginurl() Happy Coding

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. Robin Thomas Freelancer visit for fresher jobs

This is the Java Script for that in your html code Block Script :-- <script language="JavaScript"> -- you can prevent going either ways by using the code line window.history.forward(x); x is 1,2... </script>
