I hate to be pendantic, but the following is the order of HTTP headers:
nedominic@is:~ > netcat -l -p 5000
GET / HTTP/1.0
Connection: Keep-Alive
User-Agent: Mozilla/4.74 [en] (X11; U; Linux 2.2.16 i686)
Host: is:5000
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png,
*/*
Accept-Encoding: gzip
Accept-Language: en
Accept-Charset: iso-8859-1,*,utf-8
