I have a really simple question. I have a website that will only respond to:
On the server side, how do I forward cname.domain.com:1234 to said address?
P.S. - I am running IIS7
In IIS 7 you be able to do this via the Reverse Proxy and Rewrite modules, I believe.
In the site settings, you'll get an "URL Rewrite" icon once installed. From there you can add rules with hostnames and ports specified.
