Except that it is not allowed in that order!

You must first tell what is the action, eg GET.

--
GET /myfile.ext HTTP/1.0\r\n
Host: www.myhost.com\r\n
\r\n
--

Every line must be terminated by ASCII values 13 (\r) and 10 (\n) and
empty line must be after last entry in request.

Good way to test how pages should be retrieved is to use telnet to test
it out before trying it on embedded environment (saves lot's time :))
