Log Out issue

[nitin_ion]

i have implemented this code on the logout button FormsAuthentication.SignOut(); Session.Abandon(); Response.ExpiresAbsolute = DateTime.Now.AddDays(-1d); Response.Expires = -1500; Response.CacheControl = "no-cache"; Response.Redirect("~/frm_default.aspx"); but when i click on back button i am able to go the previous page.

i think u have to add Headers to restrict Back view Try this Response.CacheControl = "no-store"; Response.AddHeader("Pragma", "no-cache"); Response.AppendHeader("Cache-Control", "no-store");

if u r using master pages, code this in page load of master page or in page load of everypage Response.Expires = 60; DateTime now = DateTime.Now.AddMilliseconds(-1); Response.ExpiresAbsolute = now; Response.AddHeader("pragma", "no-cache"); int timeout = (Session.Timeout + 1) * 60; Response.AddHeader("Refresh", timeout.ToString()); Response.AddHeader("cache-control", "private"); Response.CacheControl = "no-cache"; if (Session.IsNewSession) { Response.Redirect("~/Default.aspx"); } and in logout Session.Abandon();

This is fine but then when i am on a page (not logged out) and then i click back button it does not take me to the previuos page. ihave to click refresh to get the page.

browser cache always remains open.. you cant erase bowser cache programmatically. Only you can do, is when user clicks anything on a page after logoff, throw some error messages.

Hi, On the Page Load write if Session("UserId")="" then             Response.Redirect("Login.aspx") end if if you click back now, the page will execute the page load na...it will go to login page. Ramesh Sambari
