SuperHttpClientChannel

Overview

The SuperHttpClientChannel class represents the client side of the sophisticated and flexible HTTP based communication channel that uses persistent connections to enable asynchronous calls and server callbacks. This channel offers the same two-way communication features as the Super TCP Channel, but works through HTTP, thus allowing it to pass through strict proxies and firewalls.

SuperHttpClientChannel is the base class for super client channels, working through HTTP:

Boolean Active { get; set; }

 

Property Active() As Boolean

AfterReceiveStream    (declared in Channel)

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.

The event gives you the opportunity to perform a login on the server (for example by calling a custom Login method, and then retry the call by setting the EventArgs' LoginSuccessful property to true. This way, your client can recover from a timed-out session to automatically logging in again, without the calling code having to consider the handling of SessionNotFoundExceptions manually.

AfterReceiveStream    (declared in Channel)

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.

 

event AfterReceiveStream: EventHandler<StreamEventArgs>;

 

delegate EventHandler<StreamEventArgs> AfterReceiveStream()

 

Event AfterReceiveStream As EventHandler<StreamEventArgs>

BeforeSendStream    (declared in Channel)

This event is triggered by client and server channels directly before a request or response stream will be sent over the network. User code can assign handlers to this event to process, inspect or modify incoming messages before they get sent out to the remote system.

The passed Stream is a MemoryStream and may be modified.

 

event BeforeSendStream: EventHandler<StreamEventArgs>;

 

delegate EventHandler<StreamEventArgs> BeforeSendStream()

 

Event BeforeSendStream As EventHandler<StreamEventArgs>

OnException    (declared in ClientChannel)

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.

This event will not be raised for SessionNotFoundExceptions. These will be handled separately by the OnLoginNeeded event.

 

event OnException: EventHandler<RequestExceptionEventArgs>;

 

delegate EventHandler<RequestExceptionEventArgs> OnException()

 

Event OnException As EventHandler<RequestExceptionEventArgs>

OnLoginNeeded    (declared in ClientChannel)

This event is raised if an SessionNotFoundException occurs during the execution of a remote request through the channel. The event gives you the opportunity to perform a login on the server (for example by calling a custom Login method, and then retry the call by setting the EventArgs' LoginSuccessful property to true. This way, your client can recover from a timed-out session to automatically logging in again, without the calling code having to consider the handling of SessionNotFoundExceptions manually.

 

event OnLoginNeeded: EventHandler<LoginNeededEventArgs>;

 

delegate EventHandler<LoginNeededEventArgs> OnLoginNeeded()

 

Event OnLoginNeeded As EventHandler<LoginNeededEventArgs>

OnTransferEnd    (declared in ClientChannel)

This event is triggered by the client channel after a transfer is completed (either the sending of a request or the receiving of a response).

 

event OnTransferEnd: EventHandler<TransferEndEventArgs>;

 

delegate EventHandler<TransferEndEventArgs> OnTransferEnd()

 

Event OnTransferEnd As EventHandler<TransferEndEventArgs>

OnTransferProgress    (declared in ClientChannel)

This event is triggered by the client channel during a transfer (either the sending of a request or the receiving of a response) whenever a new block of data has been sent or received.

 

event OnTransferProgress: EventHandler<TransferProgressEventArgs>;

 

delegate EventHandler<TransferProgressEventArgs> OnTransferProgress()

 

Event OnTransferProgress As EventHandler<TransferProgressEventArgs>

OnTransferStart    (declared in ClientChannel)

This event is triggered by the client channel when a transfer (either the sending of a request or the receiving of a response) is about to be started.

 

event OnTransferStart: EventHandler<TransferStartEventArgs>;

 

delegate EventHandler<TransferStartEventArgs> OnTransferStart()

 

Event OnTransferStart As EventHandler<TransferStartEventArgs>
