[Typo3] domain redirection to subfolders

[Christoph Koehler]

Hey all,

I read the getting started manual part about multiple domain, and it says:

Configure your web server to direct all requests for the three domains to  
the directory with the TYPO3-website (.../quickstart/) - now a visit to  
any of the three domains will end on the "FC Bigfeet" main site.

How would I do that? With php, or mod_rewrite or redirect?

Thanks!

Christoph
