apache log question? Is this a bad DNS on the clients side?

I have a smal web server running.

In checking the logs I see entries like:

202.102.145.162 - - [26/May/2001:07:17:36 -0400] "GET http://www.ebay.com/
HTTP/1.1" 401 484
61.137.62.80 - - [27/May/2001:10:08:22 -0400] "GET http://www.adm.com/
HTTP/1.1" 401 484
61.134.126.138 - - [29/May/2001:14:51:52 -0400] "GET x HTTP/1.0" 400 331

211.163.26.27 - - [30/May/2001:06:20:33 -0400] "GET http://www.s3.com/
HTTP/1.1" 401 484

and in my error_log

[Tue May 29 14:51:52 2001] [error] [client 61.134.126.138] Invalid URI in
request GET x HTTP/1.0
[Wed May 30 07:29:44 2001] [error] (22)Invalid argument: getsockname


The setup is when our IP is hit with a port 80 request, a username/password
box appears

My questions are:

1. Why are there URL's in the GET's? I tried playing, if I typed in the URL
as a filename
   ie: http://our.ip.address/http://www.ebay.com then the log would show
   "GET /http://www.ebay.com...." How did the GET get that URL?

2. The getsockname error occured, but there is no corresponding access log
for that time frame


I didn't find anything in the apache man files or the tutorials to explain
these entries as I
see them in the logs

Any Ideas on what these are? Is this some kind of exploit?

Thanks.
