[squid-users] reverse proxy configuration still MISSes some pages which should be a HIT....

Hi.

I'm using squid 3.1.16, compiled from source with:
./configure --prefix=/usr/local/squid-3.1.16/ --enable-useragent-log
--enable-referer-log --disable-ident-lookups --with-large-files

Running on a 64bit Debian 6 box.

If I send a request: Sent by doing: cat file | nc proxy.example.com 80

If I send the same request, but leave out the "If-None-Match", I get:

Hmm... I *think* the needed lines from squid.conf would look like,
but please correct me if this is not enough to determine the cause:

http_port 1.2.3.4:80 accel defaultsite=www.example.com vhost ignore-cc

cache_peer 1.2.3.99 parent 80 0 no-query originserver name=myAccel

Now, is there a simple(ish) way of throwing away / ignoring that
"If-None-Match" header, or configure squid in other ways, to go to the
cache, and create a HIT?

Thanks,
