[squid-users] Interminted TCP_DENIED

I've simplified things as far as I can think to and still get what appear to
be random TCP_DENIED/407 errors after I've been authenticated.

Using Squid 2.7 STABLE 9, I'm now just using the digest_pw_auth
authenticator with a single user pw file of test:test.

If I turn off authentication there's no problem. But with authentication on
I can't get much further than a page or two of sites like Yahoo.com or
LATimes.com (sites with many resources) before I get a 407.

I've run some wireshark captures and could post the http header
request/responses if that helps any. I don't know the digest authentication
protocol well enough to follow all the nonce transitions and all of that to
see if it's a problem.

Here is my squid.conf in hopes that someone might have some ideas on
direction I could take in debugging this.

Is there any way to get more info from Squid about why it's throwing 407's?
