For future reference, I believe the problem I described was fixed sometime between 3.1.19 and the current 3.2.3. I just pulled down the source to 3.2.3 and ran it with my exact same url_rewrite_program and I no longer have any problems with URL parameters. Everything works as I would have expected originally (and it still fails with 3.1.19). Time to move on to the next task. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/bug-in-url-rewrite-program-handling-of-URL-parameters-tp4657037p4657130.html Sent from the Squid - Users mailing list archive at Nabble.com.
