How Do I Select Different Home Pages?

[htscpl]

How do I send my members to different home pages?

I have several domain names but have them all pointing to a single domain. I use VBAvance for a home page and would like to create home pages for each of the feeder domains.

My thoughts were to set a variable from the referer then pass it to Vbulletin.
So what is the best way, thrucookies, private profile field, or CSS ?

Any suggestions would be greatly appreciated.
