Sorry about the wierd subject line, frankly I don't even know what to call this method of nav but hopefully the subject gives some hint. Basically I have a client that wants to have a site set up within his domain that is accessed by adding: site.domain.com ... just like yp.yahoo.com is a site within the yahoo.com site. How is this different from the standard domain.com/site.html, and how do you pull it off? I realize this could be a bigger can of worms then I realize (or a smaller one for that matter!), but I guess the only stupid question is the one you don't ask, and since I don't see this method a lot nor have I ever read anything about it I'm a tad ignorant... ok I'm *totally* ignorant. Thanks for any help!
