Member Functions

redirect virtual

virtual void redirect(
const std::string & uri,
HTTPStatus status = HTTP_FOUND
) = 0;

Sets the status code, which must be one of HTTP_MOVED_PERMANENTLY (301), HTTP_FOUND (302), or HTTP_SEE_OTHER (303), and sets the "Location" header field to the given URI, which according to the HTTP specification, must be absolute.

Must not be called after send() has been called.

requireAuthentication virtual

virtual void requireAuthentication(
const std::string & realm
) = 0;

Sets the status code to 401 (Unauthorized) and sets the "WWW-Authenticate" header field according to the given realm.

send virtual

virtual std::ostream & send() = 0;

Sends the response header to the client and returns an output stream for sending the response body.

The returned stream is valid until the response object is destroyed.

Must not be called after sendFile(), sendBuffer() or redirect() has been called.

sendBuffer virtual

virtual void sendBuffer(
const void * pBuffer,
std::size_t length
) = 0;

Sends the response header to the client, followed by the contents of the given buffer.

The Content-Length header of the response is set to length and chunked transfer encoding is disabled.

If both the HTTP message header and body (from the given buffer) fit into one single network packet, the complete response can be sent in one network packet.

Must not be called after send(), sendFile() or redirect() has been called.

sendContinue virtual

virtual void sendContinue() = 0;

Sends a 100 Continue response to the client.

sendFile virtual

virtual void sendFile(
const std::string & path,
const std::string & mediaType
) = 0;

sent virtual

virtual bool sent() const = 0;

Returns true if the response (header) has been sent.
