Thanks for the help, but I'm afraid it hasn't solved the caching problem, at least not with respect to the PHP random function... It's not as if the entire page get's cached, since there is an SQL query that selects a random row from a table--and that is random. But the PHP part of it--that is, where the background image of a table row is randomly selected--is static. Refreshing doesn't help, nor does this code, which I put in my header.inc file:
<?php header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past header ('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified header ('Cache-Control: no-cache, must-revalidate'); // HTTP/1.1 header ('Pragma: no-cache'); // HTTP/1.0 ?><html> <head> <title>My Site</title> <META HTTP-EQUIV="Expires" CONTENT="0"> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <link rel="stylesheet" href="../common/styles.css" type="text/css"> <script language="JavaScript"> <!-- You'll notice that I've got both that header function AND a meta tag, each of which should tell Apache not to cache, but here's what I think is happening: Apache is NOT caching, since the SQL select statements are running randomly. I think the cache problem is with PHP/Zend, since I'm using PHP4. So... Is there a way to force PHP to reexecute every time without configuring the server differently (since I can't)?? > -----Original Message----- > From: Julio Nobrega Trabalhando > [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, October 30, 2001 9:31 AM > To: [EMAIL PROTECTED] > Subject: [PHP] Re: Weird caching problem with PHP4/Apache > > > These lines will do what you asked, but I am unsure if they will resolve > your problem (since I don't know Fatcow and how they configured > the server). > Anyway, here it is: > > > header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past > header ('Last-Modified: ' . gmdate('D, d M Y H:i:s') .
