Help! on stop refresh.

I am taking ' How to build a members area ' tutorial of Ben. It is going well, but I have a question that someone might help me. The question is: everytime I login and then logout it causes me no problem, but if I use the back button on the browser and backing to the point that I logged in, it still keeps all my info in the login form and then log me in again. Is there any way that I can stop this? Please help!

This is a link that you can check:
Please try this

Username: demo
Password: test

When you login, logout and then use back button to go back you will see what I mean.

Thanks,

Where are all the experts? Are you on vacation? Please help me! I have put lots of hours on this but couldn't figure it out.

wareseeker,

Can you post a snippet of code you're using for this? I'm curious to see how you're handling the "logout" functions.

Try setting the page caching.

javascript:
<META HTTP-EQUIV="Expires" CONTENT="0">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">

ASP:
<%
Response.Buffer = True
Response.ExpiresAbsolute = Now() - 1
Response.Expires = 0
Response.CacheControl = "no-cache"
%>
