How to disable the back button after Session has destroyed?

Question

I want that after Logging Out any user should not be able to go to the Back Page. How can i do that?

Answer 1

AFAIK, you can not disable back button of web browser.

Add the following

"if user is logged in"

<% Response.CacheControl = "no-cache" %>
<% Response.AddHeader "Pragma", "no-cache" %>
<% Response.Expires = -1 %>

Answer 2

Clear the cache instead, it's more reliable.

Add these to your header section of the page :

<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
<META HTTP-EQUIV="EXPIRES" CONTENT="0">

And add this to your page load :

Response.Cache.SetCacheability(HttpCacheability.NoCache);

Answer 3

You could try setting no-cache on the pages viewed by authenticated users, that should requier the users browser to reload the page from the server.

Answer 4

Disabling the back button is not possible, perfectly. So you can:

1. Close the window on Log off.
2. On each page, check for a valid session and if not found, redirect to login page.
