I have my main domain, widget.com, hosted on one server because it requires cold fusion. I have another application, which needs php, that I would like to run on a subdomain, function.widget.com and link them together. Can I have the subdomain reside on a different server where php is available while the main domain is on the original server working with cold fusion?
I would think so, but I don't want to make plans around something that isn't going to fly.
I've done the exact same thing on a few sites.
I simply set up the hosting for the subdomain at the host I wanted, then created an A record for the subdomain I wanted and pointed it to the IP address of the new host.
For example, you might want to test a new version of a site, and have: [new.example.com...] on a different server to experiment with.
Or, you might want to serve images from a specialized server at [images.example.com...] that has a specialized webserver that doesn't support CGI/PHP/MySQL, etc.
Or, you might purchase a new script, and don't want it to affect a production server that is working perfectly. So, you get a cheap account at a shared host, and have it handle [messageboard.example.com...] for instance.
