Cannot prevent return to "secure" page using browser back button


Recommended Posts

Hi,

 

I am using "Login - Redirect v1.3" public_domain script published at mpdolan.com

 

Problem:

After "logout" and redirection to the "default URL" the doain name - when I click on the browsers (IE) back button I am able to (re)access the "secure/private" page I just exited. Only once I click the browser's "Refresh" button *after* returning to the private page am I denied access.

 

On my local development "server" (xampp on a Win XP machine) this "caching" does *not* occurr - access is denied immediately upon using the back button.

 

phpinfo verifies that my php.ini environment is the same as the hosting server other than (host vers = 5.0.4 & my_local ver = 5.2.3)

 

I have tried every combo of PHP "header", "session_cache_limiter()" and "session_destroy()" in my pages - *all* of wich work fine locally but *none* of which work on the hosting server - HELP please!!!!

 

I am using a sub-domain of a site with a functional oscommerce shopping cart to test this "secure" site for later implementation.

 

I obviously do *not* want to change any default settings for the entire domain since the database is common to the oscommerce cart that is "live"!

 

Thanks for any help.

You're host may not allow destroying sessions, I've never heard of a host doing this, but then again I've always been more of a root type of guy.  Have you tried manually resetting the $_SESSION values on log out.  Like...

 

$_SESSION['username'] = '';
unset($_SESSION['username']);

 

Perhaps if you post the code that builds the session and the code that handles authentication the folks on here can better assist you  :-\

Appreciate the response - will try this as soon as I get the chance (got a busy day today  :P ) and post the result and the code you suggest later

 

Thanks again.
