Im getting logs such as

"GET
http://www.escorts-etc.com/cgi-bin/ftop100/rankem.cgi?id=gagvault
HTTP/1.0" 200 147 " http://www.gagvault.com/linkspage.html";
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"

In some of my httpd access logs, even though this type of site is
not existant on the server. Anyone seen this before??


Some mis-configured Apache servers will act as an open proxy; that appears to be what this request is.  Given that it's 
logged as a 200 OK, I'd say that you have that!

Since it looks like a hit counter - "rankem.cgi" - someone is using your bandwidth to pad their click rates.

Better check your configurations!
