I have one instance of squid is configured for forward web proxy and accelerator for OWA (per the wiki). In order for users to avoid changing their proxy settings, I need the forward proxy to be able to access OWA going out and back in as follows: Host on internal net -> forward proxy -> accelerator -> OWA server on internal net It seems like this should work. When I try to access OWA from an internal host, the browser hangs and the following eventually appears in access.log: 1233516965.141 12567 [internal host IP] TCP_MISS/000 0 CONNECT owa.domain.com:443 - FIRST_UP_PARENT/[owa server IP] - Any ideas would be most appreciated. Thanks, Alan
