Hello, When trying to use squid as a front end to our Outlook Web Access server, in the following configuration: Internet<--https port 443-->firewall1<--->https port 443<--->squid box<--->https port 444<--->outlook web server I see the following in my log (aka, from a squid -d 9): ERROR The requested URL could not be retrieved While trying to retrieve the URL: http://webmail.domain.com/ The following error was encountered: * Unable to forward this request at this time. This request could not be forwarded to the origin server or to any parent caches. The most likely cause for this error is that: * The cache administrator does not allow this cache to make direct connections to origin servers, and * All configured parent caches are currently unreachable. Your cache administrator is root.
