Re: [squid-users] Why no graphics?

Hey,

I'm behind a packet filtering firewall (IPFW on FreeBSD 4.5) that *all*
traffic goes through, so it should not affect Squid in particular.

I should be more specific in that the images (for example from
http://images.google.com/images?q=july+4th&svnum=10&hl=en&lr=&ie=UTF-8&oe=UTF-8&start=20&sa=N)
do eventually show up but it's slow as an ant carrying a piano.

Access.log shows a whole bunch of TCP misses, like so:
1026269112.638 466 10.0.0.11 TCP_MISS/200 5570 GET
http://images.google.com/images? - DIRECT/216.239.51.126 image/jpeg
1026269233.617 224 10.0.0.11 TCP_MISS/200 5262 GET

http://images.google.com/images? - DIRECT/216.239.33.126 image/jpeg
1026269233.829 434 10.0.0.11 TCP_MISS/200 3516 GET
http://images.google.com/images? - DIRECT/216.239.51.126 image/jpeg
1026269233.887 491 10.0.0.11 TCP_MISS/200 5614 GET
http://images.google.com/images? - DIRECT/216.239.51.126 image/jpeg

Cache.log does not seem to show anything unusual either:

I hope this helps, let me know if I can supply anything else.

Cheers,
Caro

P.S. 10.0.0.1 is the local DNS that all my systems use without problems.
