I got a couple lines in my apache error log that I don't understand. It looks like requests to some other URL. How did they get resolved to my IP? Or could they be embedded in a HTTP request to my url? Requests with error response codes 404 Not Found http://proxy.us.pl/azenv.php: 1 Time(s) http://www.searchpost.net/azenv.php: 1 Time(s)
