Right now *.foo.com and *.bar.com are aliased to the same vhost with LAMP. Right now it, of course, shows the same content with every URL. But I don't actually want this to be what happens, and I want the other domains to actually redirect to foo.com. I'm assuming this is possible with the .htaccess file.
EDIT: I'm hosting this on my own server, so I'd also like the IP address to redirect to foo.com
