Description:
------------
After poking around with wireshark I found that GET requests made without sending 
the following header:
Cookie: COUNTRY=USA%2Cxxx.xxx.xxx.xxx; LAST_LANG=en
return a 400 from the server.

Test script:
---------------
GET / HTTP/1.1
User-Agent: Opera/9.80 (Windows NT 6.1; WOW64) Presto/2.12.388 Version/12.11
Host: php.net
Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/webp, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1
Accept-Language: en-US,en;q=0.9
Accept-Encoding: gzip, deflate
Cache-Control: no-cache
Connection: Keep-Alive


Expected result:
----------------
HTTP/1.1 200 OK
Server: myracloud
Date: Thu, 13 Dec 2012 17:24:48 GMT
Content-Type: text/html;charset=utf-8
