Does anyone have any experience allowing traffic to the Apple iTunes Music Store, through ISA2004? I have a user who needs to download some work-related stuff from there. When he tries to connect to the store he gets an error: --------------- iTunes could not connect to the Music Store. An unknown error occurred (502). Please make sure your network connection is active and try again. --------------- He tells me that the Apple web site says: Make sure your proxy allows access to these domain names: phobos.apple.com, phobos.apple.com.edgesuite.net, and passes TCP port 443 (SSL) along with, of course, HTTP port 80. I have policies that allow 443 and 80 traffic to pass, so there's nothing obviously wrong. Anybody have experience with this? Thanks, Rob
