Wouldn't it be easier to use standard HTML/CGI scripting to determine the
browser address, and display one page or another based on it's IP address?
I think that could probably be accomplished with about 15 mintues of work,
and not much thought.
This is standard for many forms to record the address of the browser that is
viewing it.
Try searching for "CGI Environment Variables" with the quotes on Yahoo, and
you'll get a lot of CGI examples you can use.

Subject: RE: forwarding surfers..
We do something like this with a combination of Apache and a Cisco
router.
On the Ethernet interface on the Cisco:
ip policy route-map SUSPENDED
access-list 192 permit tcp 192.168.0.0 0.0.0.255 any eq www
route-map SUSPENDED permit 10
match ip address 192
set interface FastEthernet0/0
set ip next-hop 65.165.120.180
!
What this does is forward all packets with a source address anywhere in
192.168.0.0/24 and connecting to port 80 to 65.165.120.180.
The next trick is getting the Unix box to accept the packets... A
little packet rewriting in IPFW:
rack0# ipfw show
00100 8964 881988 fwd 65.165.120.180 tcp from 192.168.0.0/24
to any 80
Any packets that arrive with a source address in the 192.168.0.0/24 get
redirected to this box.
Apache has a custom 404 error page. No matter what web page a customer
with a 192.168.0.0/24 address requests they get the custom 404 error
page ("Pay up bum - your account is toast").
