Thanks Amos, removing hierarchy_stoplist solved my query-string issue. However, I'm not sure what you meant by removing cache/no_cache controls. I can't see any such operators in my squif.config file. Can you please elaborate more? Thanks again. -----Original Message----- From: Amos Jeffries [mailto:squid3@xxxxxxxxxxxxx] Sent: Wednesday, April 14, 2010 6:17 PM To: squid-users@xxxxxxxxxxxxxxx Subject: Re: Reverse Proxy Cluster Issues On Wed, 14 Apr 2010 08:13:01 -0500, <senad.cimic@xxxxxxxxxxxxxxxxxx> wrote: > Hi, > > I am first time squid user and was wondering if could get some help.

The relevant lines are hierarchy_stoplist (prevent peers being asked for query-string URLs). and cache/no_cache controls (prevent "QUERY" ACL matches being stored locally.) Both of which need to be removed from your config. Amos
