Author Is this an attack?

Greetings:

I've noticed something very weird in the Apache access_log. I'm not
sure what these entries mean. Could someone help me out? We're running
Apache on a Mac OS X Server.

The entries occurred on April 20 and 24. I'm not sure why the server
would return an HTTP return code of 200 on these requests.

61.182.133.232 - - [20/Apr/2004:08:56:09 -0600] "GET
http://bliao.com/?USER=000&PASS=000 HTTP/1.1" 200 1456\

At the client some crooked DNS or host table is misdirecting these two

Or perhaps trying to use his server asa proxy. (Apache can be configured
to act as one and this person or persons could be tesing.)
