So I fired up 3.2.0.2 today. I was not able to reproduce the intermittent 407 problem in this version as predicted by Amos. However I did run into some other issues: 1) A bug with digest authentication - Open a browser and authenticate. Now restart squid (don't close the browser) Try browsing to another page. This crashes squid with the following error in squid.out: "FATAL: Received Segment Violation...dying." It probably doesn't like receiving auth headers without following the typical challenge/response process. 2) Question: Is url_rewrite_concurrency gone? I get a config file warning that it's not recognized. But it's in the squid.conf.documented docs as valid. I tried testing in 3.2.0.2-20100920 but "make install" fails with: forward.cc: In member function 'void FwdState::doneWithRetries()': forward.cc:562: error: 'class BodyPipe' has no member named 'expectNoConsumption' Would you like me to post #1 in bugzilla?
