Hi, it's me again. Due to the fact, that no one responded to this email, I will resend it.. If I wasn't clear in stating a problem, please write me, I will try to explain it again. I just don't know how to force squid to change expires header after receiving 304 not modified from server ... :( Regards, Peter > Hi, > I'm using: Squid Cache: Version 2.6.STABLE13 > > I'm caching in accelerator mode(or should I say - reverse proxy), for > example pictures, with 6hours expiry time.
