Default Strange queries in httpd log

How is it possible that I get this kind of queries on my webserver
(extract from httpd access log):

58.218.199.250 - - [22/Feb/2012:15:23:06 +0200] "GET
http://financeande.com/feed/feed.php HTTP/1.1" 404 291 "-" "Mozilla/4.0
(compatible; MSIE 6.0; Windows NT 5.1)"

...when the DNS shows that the domain financeande.com is hosted
elsewhere? What kind of query can they have used?

a forged one with a bogus vhost.

I get almost similar entry, if I hit this on the browser:

http://www.my_real_domain.com/http://bogus.com

It shows like this in the log:

> (...) - - [24/Feb/2012:11:12:27 +0200] "GET /http://bogus.com
HTTP/1.1" 404 292 "-" (...)

Only here it starts with a slash (/http...), but in the original log
entry there was no slash. I'm still curious to know how this log entry
was born:

> "GET http://financeande.com/feed/feed.php HTTP/1.1" 404 291 (...)

It was a check for proxy.
you can try something like this:

$ telnet www.my_real_domain.com 80
Trying ...
Connected to www.my_real_domain.com.
Escape character is '^]'.
GET http://financeande.com/feed/feed.php HTTP/1.1
host: www.my_real_domain.com
[double enter]

Thanks. It's good to know, even though I was pretty sure already it's
not a vulnerability.
