In transparent mode things are working for me just fine including access to battle.net and using the battle client. Does battle.net support proxy configurations? i.e. are you putting the squid IP and Port as a proxy for the client app to use? -----Original Message----- From: nuhll [mailto:nuhll@xxxxxx] Sent: Wednesday, August 20, 2014 9:51 AM To: squid-users@xxxxxxxxxxxxxxx Subject: Re: server failover/backup I found out why. If i go direct to http://llnw.blizzard.com/hs-pod/beta/EU/4944.direct/Updates/hs-6187-6284-Win _deDE-final.MPQ it works (without proxy). If i enable proxy, it wont work and i get 503.
