IpTcpClientChannel

constructor

IpTcpClientChannel()

Sub New()

This event is triggered by client and server channels directly after a request or response stream has been received and before the stream gets parsed into a message. User code can assign handlers to this event to process, inspect or modify incoming messages, before they get handled by the Remoting SDK framework. The passed Stream is a MemoryStream and may be modified.

If no handlers are assigned to the AfterReceiveStream event, the message will load the data directly from the incoming medium (usually the network stream); assigning event handlers to AfterReceiveStream will induce a slight overhead as the data will first be copied into a local memory buffer for the event handler. This should not have any noticeably effect except for very large messages or on resource-limited systems such as Compact Framework Clients, but if utmost performance is important, take this note into consideration.

property IsBusy: Boolean read;

Boolean IsBusy { get; }

ReadOnly Property IsBusy() As Boolean

Controls whether to use HTTP Keep-Alive to keep the connection alive between requests.
If enabled (true), once a request is made and a connection is established, this connection is kept open and used for future requests.
If disabled, the connection is closed, and a new connection is created for future requests.
Since establishing a connection is - relatively speaking - a costly and resource intensive operation for the network, compared to sending small amounts of data, it is recommended to keep this option enabled for optimal performance, if requests to the server are done relatively frequently.
For Keep-Alive to work, the option must be supported and enabled on both client and server.

property KeepAlive: Boolean read write;

Boolean KeepAlive { get; set; }

Property KeepAlive() As Boolean

This method acts as event handler for the Connection actually performing the network operations. It is added and removed via HookUpConnectionEvents and UnhookConnectionEvents.

This event is raised if an exception occurs during the execution of a remote request through the channel. The event will be raised both for exceptions originating from the server and for exceptions during communication (such as unavailability of the server). Attach a handler to this event to do custom handling of events without having to reply on explicit try/catch blocks in the calling code.
