Re: [squid-users] Re: Squid 3.4 Head can't cache static url

I think it's a squid -> server message, and the cache is nginx.

Hey Amos, squid will always respond with a MISS to requests with
"Cache-Control: max-age=0" ? There's a way to ignore it with
configurations? I'm thinking about windows updates, MS probably sets
that to zero. In what other situation a client does this?
