Thank you, Amos -- it had to do with the dual NICs on the server, and weird routing between the two subnets represented.

Ensuring the presence of a Content-Length header can prevent Squid falling back on disk storage for temporary unknown-length objects. And a cache_mem at least big enough to store the required in-transit ones lets them fly past quickly. I don't think that is related to the problem though. > When I set Firefox to NOT use the procy, there I no slowdown, I get > immediately prompted for uid/pw. > Amos -- Please be using Current Stable Squid 2.7.STABLE9 or 3.1.6 Beta testers wanted for 3.2.0.1
