Another way is to write a javascript function which reads value of a hidden field, say isLoggedIn, and if found false, forwards the page by using window.history.forward(1), so that the effect of the back button is reset.

The isLoggedIn hidden field will be set to true or 1 when the user logs in and it will be set to false or 0 when a user logs out.

This script should be incorporated in the header of every aspx page and every page should have a hidden field like isLoggedIn.

both of solutions are good.

1st one is more suitable , as you are already using session . and if session expired adn user requested for back button he/she will be redirected to login page.

problem in javascripting is that you need to use it on every page

<Script>

ASP.NET users can try this code and php users can convert this

In logout page embed this on page load event

Session.Aandon()

Dim strURL as string= "login.aspx"

Response.Write("<script language='javascript'>")

Response.Write(" window.open('" & strURL & "','_self','toolbar=1,<BR>location=1,directories=1,status=1,menubar=1,<BR>scrollbars=1,resizable=1'); ")

Response.Write("</script>")

Session.Abandon have no effect on the client side. If you want to disable a back button, you can write the javascript code in window_onunload, in submit_click event, write the code

document.form1.Text1.size = 19 (any value) (Suppose orgininal size is 20)

then in the onunload event of window,

if(document.form1.Text1.size != 19)

window.location = full path of your current page.

It is working fine in my page.If you have doubts, sanju1_john@rediffmail.com

<a herf="webform name" onclick="javascript:location.replace(this.href);event.returnValue=false;">no back page </a>
