Can PHP be set to never cache a response, and always send something fresh to the page? -


i have webpage pulls in xml news feed , don't want page cache xml feed displayed recent.

i tried cache reset every 1800 seconds:

$header[] = "cache-control: max-age=1800";

didn't seem work.

so try make webpage auto refresh xml in php?

try this,

<?php header("cache-control: no-cache, must-revalidate"); // http/1.1 header("expires: sat, 26 jul 1997 05:00:00 gmt"); // date in past ?>

this prevent page being cached on user's machine.
