what's this log entry indicate?

Folks--

Recently I've been noticing apache log entries like the following:

218.94.83.20 - - [14/Aug/2003:22:47:01 -0400] "GET 
http://www.intel.com/ HTTP/1.1" 200 1357

What's going on here?  That's a pretty strange file path for my server. 
 It looks like an attempt to use my server as an HTTP relay.  Despite 
the 200 response I don't think it worked--my index page ("/") happens 
to be 1357 bytes long.

Also, does anyone have poiners for setting up apache to return either 
403 or 404 for such malformed page paths.

Thanks,
