[PHP-DB] Expires Pages

2001-03-20 Thread Marcelo Pereira 

Hello,

I'd like the user of my site to log in/out, but, how can I disallow the user to press 
the 'back button' of the browse after logout, and back to the page ???

What I need:

- The user press 'logout';
   if (user press the 'back button' of the browser) then
  show a page telling that the page expired just when the user clicked at logout.
   fi

I was reading about cookies, I think I have to go in this direction, but, how ???

Thanks in advance,

See ya.

this should work ... in the top of the page, before any other headers are
sent

?php
header ("Ex-pires:Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
// al-ways modified
header ("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header ("Pragma: no-cache"); // HTTP/1.0
?
