RFC 1945 http://tools.ietf.org/html/rfc1945

The Hypertext Transfer Protocol (HTTP) is an application-level protocol with the lightness and speed necessary for distributed, collaborative, hypermedia information systems. Messages are passed in a format similar to that used by Internet Mail and the Multipurpose Internet Mail Extensions (MIME). (Compliant with IETF RFC1945 May, 1996.)

Request Packet

The format of the Request packet header is shown in the following illustration:

Method

Request URI

HTTP version

HTTP request packet structure

Method
The method to be performed on the resource.

Request-URI
The Uniform Resource Identifier, the resource upon which to apply the request, i.e. the network resource.

HTTP version
The HTTP version being used.

Response Packet

The format of the Response packet header is shown in the following illustration:

HTTP version

Status code

Reason phrase

HTTP response packet structure

HTTP version
The HTTP version being used.

Status-code
A 3 digit integer result code of the attempt to understand and satisfy the request.

Reason-phrase
A textual description of the status code.
