    /* Google Code's messing up with requests, use HTTP/1.0 as suggested. More info:

       http://code.google.com/p/support/issues/detail?id=6095

       Of course it would be still too simple, coz IE will override settings, so
       you have to disable HTTP/1.1 manually and globally. More info:

       http://support.microsoft.com/kb/258425

       So this code's basically useless since disabling HTTP/1.1 will work with the
       above code too.

       Update: a Connection: close header seems to disable chunked encoding.
