ASP Login system with MySQL

1) I do wish to create a ASP Login, Verification, Logoff, Display database information page via MySQL support. I tried but then I did not succesfully do the secure pages which when I click the backward button, all information still there even I have logged off from the system.
Please kindly attach some sample of the pages for references.

2) Under your own opinion, which format of languages do you think is better between the ASP and PHP for the secured login and logoff system.

Thank you so much!

Use a session object to set the user's permission level, then just request the session object on each page.  Here is an example.

ok, what can we do here?

Let me tell you that I use ASP, so i can´t tell you nothing about PHP, but, if i´d had to do that, i´ll do the following:

1. I´ll put these meta tags in the head section to make the pages load every time instead of putting it in cache:

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

2. Make a redirect page in the middle of the log off process, (just like in hotmail), when people press log out, direct them to a page. set the session vars to nothing and then redirect to the successfull log out page, these will help in some way.

then, when people press the back button, tha page will see that the session var is nothing and will send them to the login page.

that should work.
