current windows username in http.conf?

[blueman378]

hi guys, im trying to get a php server up and runnig at school, i have it working fine if the document root is left at its default, currently S:\server\htdocs (example)

 

However when a user is created they get a folder in thier profile called My Websites

I am trying to map the documetn root to this drive,

 

The drive is mapped as H:\ for all users however the physical place is U:\USERNAME\My Websites

 

If i try using H:\ it does not work, so is it possible in the http.conf file to set the doc root to something like U:\%current_user%\My Websites ?

 

cheers, Matt
