Hello squid-users, I'm successfully using Squid (3.0.STABLE25) with ESI enabled but, I can't seem to cache anything that has a cache-control: max-age less than 60 seconds. At present I'm having to set cache-control: max-age header at 61 seconds in order to cache. e.g; <?php header('Surrogate-Control: s-maxage=61, content="ESI/1.0"'); header('Cache-Control: max-age=61' ); ... ?> Am I missing something? Regards, Jonathan
