[squid-users] ActiveSync stopped working in reverse proxy

Hi -

I have a Squid3 reverse proxy set up for SSL offloading.  It has been working fine until 48 hours ago for ActiveSync users.  If I bypass the proxy (NAT around it) they can connect fine.  Below is a <EDITED> snippet from the cache.log in debug mode:

It appears to connect and then hangs.

Thanks in advance,
