Detailed Description

A Connection object represents the state (and socket) for an ongoing, active, HTTP Connection, managed by the ConnectionManager class.

This tends to get used internally by the ConnectionManager, but you can use it directly. For example:

Example Usage

Connection conn{acceptedSocketConnection,
             Connection::Options{.fInterceptorChain = Sequence<Interceptor>{
                Interceptor{
                    [=](Message* m) {
                        Response& response = m->rwResponse ();
                        response.rwHeaders().server = "stroika-ssdp-server-demo";
                        response.write (Stroika::Frameworks::UPnP::Serialize (d, dd));
                        response.contentType = DataExchange::InternetMediaTypes::kXML;
                     }}}}};
conn.SetRemainingConnectionMessages (Connection::Remaining{0, 0}); // disable keep-alives
conn.ReadAndProcessMessage ();

Member Function Documentation

ReadAndProcessMessage()

Connection::ReadAndProcessResult Connection::ReadAndProcessMessage ( )

noexcept

Return eTryAgainLater if 'keep alive' (or otherwise should try again - like incomplete input).

Delegate to interceptor chain. This is the principle EXTENSION point for the Stroika Framework webserver. This is where you modify the response somehow or other (typically through routes).

Member Data Documentation

socket

const Common::ReadOnlyProperty<ConnectionOrientedStreamSocket::Ptr> Stroika::Frameworks::WebServer::Connection::socket

This returns the (two way) connection oriented stream socket (ptr) used by this connection.

Definition at line 135 of file Frameworks/WebServer/Connection.h.

request

const Common::ReadOnlyProperty<const Request&> Stroika::Frameworks::WebServer::Connection::request

Access a (read-only) reference of the underlying connection request

Definition at line 141 of file Frameworks/WebServer/Connection.h.

response

const Common::ReadOnlyProperty<const Response&> Stroika::Frameworks::WebServer::Connection::response

Access a (read-only) reference of the underlying connection request

Definition at line 147 of file Frameworks/WebServer/Connection.h.

rwResponse

Common::ReadOnlyProperty<Response&> Stroika::Frameworks::WebServer::Connection::rwResponse

Access a (read-only) reference to the underlying (modifiable) connection response (meaning you cannot assign to the response itself, but you can modify the response object)

Definition at line 153 of file Frameworks/WebServer/Connection.h.

stats

const Common::ReadOnlyProperty<Stats> Stroika::Frameworks::WebServer::Connection::stats

retrieve stats about this connection, like threads used, start/end times. NB: INTERNALLY SYNCRONIZED

remainingConnectionLimits

Common::Property<optional<HTTP::KeepAlive> > Stroika::Frameworks::WebServer::Connection::remainingConnectionLimits

Note

set Remaining::fMessages := 0 to prevent keep-alives.

Example Usage

conn.remainingConnectionLimits = KeepAlive{0, 0}; // disable keep-alives
