IPDaemonS Component [IP*Works! SSL V8]

Properties Methods Events Configuration Settings

The IPDaemonS component is used to create TCP/IP servers. The component handles multiple simultaneous connections on the same TCP/IP port (service port). It is designed to balance the load between connections for a fast, powerful server.

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks

The IPDaemonS component is the SSL-enabled equivalent of the IP*Works! IPDaemon component. The main difference is the introduction of a set of new properties and events that deal with SSL security. The SSLProvider configuration setting chooses a security provider subsystem. The SSLEnabledProtocols and SSLCipherStrength configuration settings determine which protocols are enabled and at what security level. The SSLCert properties are used to select a certificate for the server (please note that a valid certificate MUST be selected before the server can function). The SSLAuthenticateClients property together with SSLClientAuthentication event allow you to use digital certificates for client authentication. Finally, the SSLStatus event provides information about the SSL handshake.

IPDaemonS is the server complement of IPPortS (which is used to create client applications). They share a common design philosophy and interface. We expect you will find IPDaemonS as easy to use as IPPortS.

By default, each instance of IPDaemonS can handle up to 1000 simultaneous incoming connections (this number may be increased up to 100,000, or decreased to a lower value by using the MaxConnections configuration setting).

The connections are identified by a ConnectionId (a number between 1 and MaxConnections). IPDaemon's events also have ConnectionId as a parameter to identify the connection they relate to.

Our main goal in designing IPDaemonS was to make it easy to use without sacrificing performance. The component has a minimum of properties, and six events: ConnectionRequest, Connected, DataIn, Disconnected, ReadyToSend, and Error.

IPDaemonS can start to listen on a port by setting the Listening property to True. When a remote host asks for a connection, the ConnectionRequest event is fired. At that point, the connection can either be accepted or rejected. If the connection is accepted, a ConnectionId is assigned, and communication can start. From this point on, the operation is very similar to IPPort. Data is sent by assigning the data string to the DataToSend property. The address and port of the incoming connection can be found by querying the RemoteHost and RemotePort properties.

Property List

The following is the full list of the properties of the component with short descriptions. Click on the links for complete descriptions.


ConnectionBacklog	The maximum number of pending connections maintained by the TCP/IP subsystem.
Connections	A collection of currently connected clients.
DefaultEOL	A default EOL value to be used by incoming connections.
