Hi, we are using squid as reverse proxy for Outlook RPC over HTTPS without any problems. Today some iPhone users/customers wanted to use Exchange ActiveSync as well so I decided to "simply" allow /Microsoft-Server-ActiveSync/* as well and hoped all is well. Far from it. The Exchange ActiveSync account on the iPhone can be setup without problems and verifies. Sending E-Mails is no problem. However receiving e-mails and e-mail push does not work at all. Whenever the user tries to receive mails I see this in cache.log: 2008/11/25 11:28:26| The request OPTIONS https://outlook.test.de:443/Microsoft-Server-ActiveSync is ALLOWED, because it matched 'url_allow' 2008/11/25 11:28:26| The reply for OPTIONS https://outlook.test.de/Microsoft-Server-ActiveSync is ALLOWED, because it matched 'all' 2008/11/25 11:28:26| Invalid chunk header ' ' 2008/11/25 11:28:26| clientWriteComplete: Object aborted 2008/11/25 11:28:27| The request POST https://outlook.test.de:443/Microsoft-Server-ActiveSync?User=testuser&De viceId=Appl88843DYCY7H&DeviceType=iPhone&Cmd=FolderSync is ALLOWED, because it matched 'url_allow' 2008/11/25 11:28:27| clientReadBody: start fd=12 body_size=13 in.offset=13 cb=0x8088430 req=0x888c000 2008/11/25 11:28:27| clientProcessBody: start fd=12 body_size=13 in.offset=13 cb=0x8088430 req=0x888c000 2008/11/25 11:28:27| clientProcessBody: end fd=12 size=13 body_size=0 in.offset=0 cb=0x8088430 req=0x888c000 2008/11/25 11:28:27| The reply for POST https://outlook.test.de/Microsoft-Server-ActiveSync?User=testuser&Device Id=Appl88843DYCY7H&DeviceType=iPhone&Cmd=FolderSync is ALLOWED, because it matched 'all' 2008/11/25 11:28:27| Invalid chunk header ' ' 2008/11/25 11:28:27| clientWriteComplete: Object aborted This seems to be the root of the problem but how do I fix it if I can fix it at all? Customer is running squid-2.7.4 against Exchange 2003. Any help greatly appreciated. Regards, JP
