Preventing Squid from resolving hostnames

Ok, after some fiddling I figured it out.

The silverlight application is irrelevant, all it does (as far as the proxy is concerned) is fetch dynamic HTTP content.

What I needed besides the basic setting was a refresh_pattern that looks like this :

refresh_pattern -i \.ashx 10080 90% 999999 ignore-no-cache override-expire ignore-private

Now I know a tiny bit more about proxy setup and how it works. Woohoo!

I would try the following config. I cleaned up yours (removed stuff not referenced) and forced it to cache anything for a year and not cache failures.

Note, squid configs are very version specific, so what version are you running?

cache_dir ufs /var/spool/squid3 100 16 256
coredump_dir /var/spool/squid3

acl localhost src 127.0.0.1 ::1

acl PURGE method PURGE
http_access allow PURGE localhost

acl manager proto cache_object
http_access allow manager localhost

acl dev_users dstdomain dev
http_access allow dev_users

http_port 3128 accel defaultsite=dev vhost
cache_peer 127.0.0.1 parent 80 0 no-query originserver name=dev
cache_peer_access dev allow dev_users
cache_peer_access dev deny all

# Don't cache 404's
negative_ttl 0

# Cache everything for a year
refresh_pattern . 1440 100% 525949 override-expire ignore-reload ignore-no-cache ignore-no-store ignore-must-revalidate ignore-private ignore-auth 

#cache JPEG but not anything else
acl JPEG url_regex -i .*image\?href=http.*api.discogs.com.*image.*\.jpeg$
acl to_localhost dst 127.0.0.0/8
cache allow JPEG
cache deny to_localhost
