Re: [squid-users] WHERE does Squid cache DNS lookups?

I'm not sure where squid stores the DNS cache. However, your test of
attempting to use a transparent proxy, is probably not sufficient. I had
a lot of trouble using the Auto-Configuration script with Internet
Explorer. I mean, a LOT. I found out that there was/is a bug in IE 5.0+
where-in, when IE sends out the auto-discovery packets, it chops the last
character off the script name. So it looks for proxy.pa instead of
proxy.pac.
When you said you got a "couldn't find page" error that wasn't from squid,
it's probably because IE didn't attempt to connect to the page through
squid, because it couldn't find your squid configuration script.

Just an fyi.

Hi folk,

When Squid does a DNS lookup, where does it save the cached entries? I
know you can
specify how many entries you want it to save but where does it actually
save it on disk?

In fact how does squid do DNS lookups? Squid is listening on port 3128 and
a DNS lookup
sends a udp packet on port 53. How does squid intercept such a lookup?

If I set my browser settings manually (non transparent), and type a
non-existing url. I
get a message from squid saying it couldn't do a look up. However, when I
make squid
transparent. I don't see the same page again. I only see a message that
says couldn't find
page (which is not from squid).
So is squid caching DNS entries??

Thanx guys... really want this to work... and help would be greatly
appreciated
