Session Problem.. (Back Button)

[Kunal P]

hi i wanted to implement sessions in my application... i wrote the following code on the login page if (dread.Read()) { Session["user"] = uname.Text; Response.Redirect("MainP.aspx"); } then on the page load event of the following pages i wrote this code..(used master pages.though) if (!IsPostBack) { if (Session["user"] != null) { Label1.Text = Session["user"].ToString() + "!!"; //Label1.Text = Session["user"].ToString(); Response.Cache.SetExpires(DateTime.Now.AddSeconds(0)); Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Cache.SetValidUntilExpires(true); } else { Response.Redirect("login.aspx"); string uname = (string)(Session["User"]); } } Now the problem is that, if i dont login, no page will open, if i type the URL, but afted logout, on BACK BUTTON press of the web browser, the page opens, instead of getting redirected to login page. any ideas.. then i created a LOGOUT LInk Button, and wrote the following code... protected void LinkButton1_Click(object sender, EventArgs e) { Session.Abandon(); Session.Clear(); Session["user"] = null; Response.Redirect("login.aspx"); }

Hi, Put the following piece of code on every page, outside of postback check if (Session["user"] == null){ Response.Redirect("login.aspx"); string uname = (string)(Session["User"]); } Mubashir

Every job is a self portrait of the person who did it.

Move the above code to the beginning of the Page_Load Event.
