[ciapug] php SuperGlobals issue

[vanish at dreamscapevisionery.com]

Ready for things to get stranger?

SO this server has two NICs with two IPs, one assigned to each NIC. In 
the vhost
setup, the first IP is assigned to the production site. The second IP has two
vhosts. I'm working on a site on one of these vhosts. In the phpinfo() output,
it shows the REMOTE_ADDR as the 2nd NIC (where the site is pushed through) yet
the SERVER_ADDR is the 1st NIC, which shouldn't even be an issue as I'm not
going to the site pushed on that IP.

The good news though is it also shows a PC-Remote-Addr which does, 
indeed, show
my IP instead of the servers. I hope I can get to that through getenv()
