Getting the domain from a request under HTTP/1.0

All,

I've got a problem that I don't think is solvable using HTTP/1.0.  Our
site here (http://www.wdi.co.uk/) is supporting multiple companies
under subdirectories.  Each of these companies has registered a 
domain name (for example, Westwind have registered westwind.co.uk that
has the IP address 193.243.226.xxx)  Now to get Westwind at the moment
you access the HTTPd with http://www.westwind.co.uk/westwind and it 
basically becomes a request to www.wdi.co.uk for the directory westwind.

Simple enough, however, some people have put out their URL as
'http://www.xxx.co.uk/' without the directory name.  My question is 
this: under HTTP/1.1 the client should send through the entire URI
in it's header (GET http://www.westwind.co.uk/ HTTP/1.1) or include 
the 'Host:' field.  However, HTTP/1.0 is not as clever and, as I have
noticed, clients don't send through the address.  So, how can I get
it from an HTTP/1.0 request?

If you're interested, the server at http://www.wdi.co.uk/ was written
by me 8 months ago.  It supports the then HTTP/1.0 protocol but hasn't
been upgraded to HTTP/1.1 yet.  I'm working on it :)

Anyway, thanks for any help,
Matt
