OT: Apache www & no www

[William Jensen <jensenb@charter.net>]

I have a forwarder setup with my domain to go from www.mydomain to mydomain
so anyone using http://www.mydomain.com will just get routed to mydomain.com.
I tried it out at work today to find it isn't working, but going straight to
mydomain.com does.  When I tail -f /var/log/apache/access.log I see a very
strange thing:

24-216-4-15.hsacorp.net - - [08/Oct/2000:17:53:18 -0500] "GET / HTTP/1.0" 304 -

This is NOT my ip.  When I did a lookup on it it is indeed my provider but
it's not me.  Why would my provider's pc be involved with this?
