Ok maybe someone knows

I'm posting again cause I got such a great response last time.
This isn't solely a linux question but *nix users should be familiar with webalizer.

It's a simple question: In the webalizer.conf file, you can set it to group sites together.
I'm trying to group all referrals by http://www.foo.com/ into one listing.

So it will group http://www.foo.com/ http://www.foo.com/audio/ http://www.foo.com/chat/ etc..
basically so that http://www.foo.com/* will be in one group of referrals. Unfortuanatly any set up
I've tried doesn't seem to work, and I end up with all kinds of http://www.foo.com/ listings.

So sorry this isn't solely about linux but can anyone help me out here that has done this before?
