i have a user trying to get to an SSL site that doesnt use port 443. and its a college site. ISA gives me the following error where can i allow this port over SSL in ISA Error Code: 502 Proxy Error. The specified Secure Sockets Layer (SSL) port is not allowed. ISA Server is not configured to allow SSL requests from this port. Most Web browsers use port 443 for SSL requests. (12204)
