I have a similar problem in that I have a 'common' web folder used by
multiple web apps, but I'm 'tricking' IIS into thinking its one big app
using virtual sub-directories pointing to this common folder (lets me use a
common CSS stylesheet and have a common directory for images etc.).. For
example -

Main App  (in say c:\inetpub\wwwroot\main, virtual directory '\main')
 \__ Child App (actually in c:\inetpub\wwwroot\child, but I want the
virtual dir to be '\main\child' rather than '\child' if that makes sense)

The web setup app seems to force the virtual directories to map to the same
physical location. You can't change the virtual path of subfolders :o(. Is
there a way to implement this?

Thanks,

Simon
