Can anybody help me with log out?

I'm creating a web site in .net that has a log in and log out.
My problem is about log out.

When you click back in previous page I want to disable the back button.

How can I do that? :sigh:

Quite a common question answered number of times!

This happens because of cache.
1. clear the sessions
2. clear the cache such that browser has no history (this will make back/forward button in browser grayed out disabled.)
code for clearing cache can be put up in code behind as follows:

C#

// Code disables caching by browser. Hence the back browser button
// grayed out and could not causes the Page_Load event to fire 
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
Response.Cache.SetNoStore();

You can add somethin similar in form aspx if you want to place it there:

<meta http-equiv="Cache-Control" content="no-cache" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0" />
