Track Visitors by Domain Name?

[tw]

A client bought a catchy new domain name to use in advertising but wants it pointed to their existing site. In order to track the effectiveness of their advertising, however, they want to know which visitors accessed their site via the catchy new domain name.

I don't see how they can track access by domain name since every way I can think of to track involves looking at what files were requested from the server, and we'd be sending catchy-domain-name-people to the same set of files as visitors going to the regular site. I think at minimum we'd have to set up hosting and a web page for the catchy domain.

Am I missing something?

If you are on an Apache server, you can log the web server name in the log file and you can test the HTTP_HOST environment variable in PHP and in other languages.

Thank you very much for your reply - I think that is what the client did. Turns out they have a decent IT staff and all they needed from me was a change of IP : )

They can of course use website logs on catchy domain name site to find the numbers. As you have said the problem is already solved !
