Description fredrik danerklint 2007-02-22 21:28:11 UTC
if you put wqSquidMaxage in your Localsettings.php to zero, then you aren't able to cache pages in Squid. 

As it is now, you will get the header "Cache-Control: private, must-revalidate, max-age=0".

With my patch of one char, you get the following header "s-maxage=0, must-revalidate, max-age=0" which still allows 
Squid to cache the page after validateing the page with Mediawiki.

... Correct me if I'm wrong, but isn't this expected? I would assume that
setting $wgSquidMaxage = 0 would mean that you NEVER want ANYTHING cached...
which is what happens.

Why would you put $wgSquidMaxage = 0 if you wanted pages cached?
