What is a Request message?
Answer:
The request message consists of the following:
► Request line, such as GET /images/logo.png HTTP/1.1, which requests a resource called /images/logo.png from server
► Headers, such as Accept-Language: en
► An empty line
► An optional message body
The request line and headers must all end with <CR><LF> (that is, a carriage return followed by a line feed). The empty line must consist of only <CR><LF> and no other whitespace. In the HTTP/1.1 protocol, all headers except Host are optional.
A request line containing only the path name is accepted by servers to maintain compatibility with HTTP clients before the HTTP/1.0 specification in RFC1945
