apache returning false 200 values

GET http://www.yahoo.com returns a 200?

[Finder]

This is really mind-boggling. Why would a GET request for a different domain return a 200 value?

218.68.227.160 - - [23/Sep/2002:14:59:28 -0400] "GET [yahoo.com...] HTTP/1.1" 200 485 "-" "Mozilla/5.0 (compatible; MSIE 5.01
; Win2000)"

I've seen this about a dozen times in my log, almost always a GET request for Yahoo or Google. With one exception, the IP address always originates in China or Latin America.

I'm running Apache 1.3.24 and I'm very new to website management. Can anyone offer any insight?

They're looking for a web proxy.
Your Apache is set up with a default virtualhost (probably), so it returns the content for that host when a host that's not otherwise configured is requested.
Don't worry about it. (unless you're running an open web proxy)
