Ok... after reading wurfl documentation, i'm not convinced. I was looking for something more along the lines of the following....

Using the http_user_agent detect if the connection is coming from a pc or mobile. Now I think that it would make sense to detect a pc browser because there are less of them compared to mobile phones. If its a pc, redirect them... if it's a mobile do nothing and display a .mobi compliant site.

and I need to do this in an asp/vbscript environment... any help greatly appreciated.
