Squid stale-while-revalidate not working when max-age=0
- by Wiliam
Squid 2.7 always reaches backend, expected is to reach backend using stale-while-revalidate only when cache expires, not when client triggers max-age=0.
Script:
<?php
header('Cache-Control: public, max-age=10, stale-if-error=200, stale-while-revalidate=500');
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
sleep(2);
die("OK");…
