Writing Regular Expressions in Apache?

Hello all,


I'm trying to configure apache to look at a series of user directories
on another server


I've added
UserDir "//server-001/*"


and found it works ... but as you may well realize, that's a bit of a
security hazzard


so i went on to try
UserDir "//server-001/*/public_html"


and found it will not work ... the error log shows that when using the
first directive
http://localhost/~username resolves properly to "//server-001/username"

however when using the second it somehow gets set to looking for
"C:/docroot/~username" including the tilde


I'm running Apache/2.0.55 (Win32) on a windows XP-Pro machine
a bug perhaps? anyone have any suggestions? there may be a way to use
regex or alias to add the trailing "/public_html" to the UserDir


I've also noticed that if i try to include (un-comment) any sort of
additional <directory> statement, i get an error when trying to start
up the
server


any ideas on a way i can get this thing up and running?
