["A.Sleep" <a.sleep@asleep.net>]

Hello all, I'm new to the list, the Geocrawler search (I'm being kind)
provided null for this topic so I'm hoping someone may have an idea of how
this is done:

An associate of mine has is system setup so that a users public_html dir has
(by default) two dirs. one www and one _ (linked to www).

When that user adds another dir (say test) it becomes a subdomain of their
domain.

e.g. DEFAULT: www.theirdomain.com ADDED DIR (test): test.theirdomain.com

I've been attempting this with mod_alias and mod_rewrite and I'm quite
exasperated. :)

Any pointers?

A.Sleep
