Increase in Web app support calls fixed by clearing browser cache

We have a LAMP Web app that passes the user to a Wndows server for a streamed media presentation when a presentation is selected from a menu.  In the past few weeks we have experienced a marked increase in the number of users reporting that they are returned to the [LAMP] login when they select a presentation.  It would appear that they are not passed to the Windows server and probably lose their php session variables which would send them back to the login screen.  In every case the problem has been fixed by clearing the cache in the browser.

No major changes recently in this portion of the LAMP Web app.   I am at a loss on how to approach this.  Is there anything that we can alter in the PHP/MySQL design to affect the browser cache usage?  ave there been recent changes to IE (used by a majority of our clients) that might be causing this?

Hi,

If caching is the problem then put the code below in a includes page and include it on all your pages where you want to stop caching. You may have to F5 (clear your history) for this to start working.

I have used it before and its a good way to make sure the page doesn't cache.

Note: As this modifys the page headers, the code must be before you output any information to the page, so before the <html> tag in your HTML and before you print or echo anything to the page.
<?php
	/* stop caching */
	header("Cache-Control: no-cache, must-revalidate");
	header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
?>
 
<?php
	/* how to include it */
	include_once 'file_name.php';
?>
