Abstract

The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems. It is a generic, stateless, protocol which can be used for many tasks beyond its use for hypertext, such as name servers and distributed object management systems, through extension of its request methods, error codes and headers [47]. A feature of HTTP is the typing and negotiation of data representation, allowing systems to be built independently of the data being transferred.

HTTP has been in use by the World-Wide Web global information initiative since 1990. This specification defines the protocol referred to as "HTTP/1.1", and is an update to RFC 2068 [33].

HTTP/1.1 has been designed to allow implementations of applications that do not depend on knowledge of ranges.

4 HTTP Message

4.1 Message Types

HTTP messages consist of requests from client to server and responses from server to client.

HTTP-message = Request | Response ; HTTP/1.1 messages

Request (section 5) and Response (section 6) messages use the generic message format of RFC 822 [9] for transferring entities (the payload of the message). Both types of message consist of a start-line, zero or more header fields (also known as "headers"), an empty line (i.e., a line with nothing preceding the CRLF) indicating the end of the header fields, and possibly a message-body.

generic-message = start-line *(message-header CRLF) CRLF [ message-body ] start-line = Request-Line | Status-Line

In the interest of robustness, servers SHOULD ignore any empty line(s) received where a Request-Line is expected. In other words, if the server is reading the protocol stream at the beginning of a message and receives a CRLF first, it should ignore the CRLF.

Certain buggy HTTP/1.0 client implementations generate extra CRLF's after a POST request. To restate what is explicitly forbidden by the BNF, an HTTP/1.1 client MUST NOT preface or follow a request with an extra CRLF.

/** * Represents a HTTP request */class Request extends Message {

/** * @var string */ protected $method = 'GET';

/** * @var \TYPO3\FLOW3\Http\Uri */ protected $uri;

/** * @var \TYPO3\FLOW3\Http\Uri */ protected $baseUri;

/** * @var array */ protected $arguments;

/** * Data similar to that which is typically provided by $_SERVER * * @var array */ protected $server;

/** * The "http" settings * * @var array */ protected $settings;

/** * URI for the "input" stream wrapper which can be modified for testing purposes * * @var string */ protected $inputStreamUri = 'php://input';

/** * Constructs a new Request object based on the given environment data. * * @param array $get Data similar to that which is typically provided by $_GET * @param array $post Data similar to that which is typically provided by $_POST * @param array $files Data similar to that which is typically provided by $_FILES * @param array $server Data similar to that which is typically provided by $_SERVER

$request->getHeader('User-Agent'); # C64

$request->setHeader('X-Coffee', 'too few');

$now = new \DateTime();$response->setLastModified($now);

$response->getHeaders()->setCacheControlDirective('s-max-age', 100);

# set cookie in response:$response->setCookie(new Cookie('counter', 1));

# retrieve cookie on next request:$cookie = $request->getCookie('counter');

Tackling the Heart of Software Development

Domain-Driven DesignA methodology which ...

• results in rich domain models

• provides a common language across the project team

• simplify the design of complex applications
