Hmm... I wonder what's wrong...
The proxy server received an invalid response from an upstream server.
Apache/2.0.49 (Unix) mod_ssl/2.0.49 OpenSSL/0.9.7c-p1 Server at minghong.webhop.org Port 80
I'm sure my server is a Windows box, using IIS and port 8080. Why
Port 80... That must be the biggest mystery of this century (*jokingly*).
