A HTTP response message contains a status line, header fields, and the requested entity as the body of the message. The body of the response is usually the resource requested in the request message. Example B-3 shows the result of a
GET method on a small HTML file.

The status line-the first line of the message-starts with the protocol version of the message, followed by a status code and a reason phrase, each separated by a space character. The status line is followed by the header fields. As with the request, each field is represented as a name and value pair separated with a colon character. A blank line separates the header fields and the body of the response.updated
