asp page with logout issues

[weiwei]

Hi
I am having a problem with my asp application. here is very simple
description. I created a user login.asp,
that user login with his username and password, once he in, he can
fill out several application forms...so on.
at the last, if user click logut, it will leave that applicaiton and
redirect to the main URL. So far, I don't
have problmes except with the logout page. B/s when I click logout and
it brings me to the main website. However,if
I click the back button from the browser, it still brings me back the
asp application. is there anyway that once
you logout, and you cann't going back to your asp application.
Below is my simple code, thanks in advance.

Disallow page caching on your session-protected pages. (I'm assuming you're
using sessions to determine if the user is logged in, but that's beside the
point.)

That's just the nature of the Back button.

But if interested you can check this out.

A1ien51's disable the Back Button

What is going to happen, is when the page loads, it will send the surfer
to the last page in their history.
Now if a person tries to go back to it, then it will send them directly
back to the page they pushed the back button on!
Add this code to the header of your page:
<script>
history.forward();
</script>

JPS: Thus need to put the code on the page you don't want the user to be
able to go back to.
And here is my version of it:
<script type="text/javascript"> <!--
// Disable browser's Back button on another pg being able to go back to
this pg.
history.forward();
//-->
</script>

But if the page you put this on uses alert boxes for validation, may see
that again.
