SIGNALR supports a variety of server and client configurations. In addition, each mode of transmission has its own requirements, and if some transmission mode is not supported by the system, SIGNALR can gracefully failover to other types of transmission mode. For more information about the transport modes supported by SIGNALR, see: Transports and Fallbacks.
System Requirements
The SIGNALR server component can be supported by a variety of server configurations. This section describes the operat
task execution node.
The task Execution node performs the task and updates the status of each request in the task Coordinator.
The Task coordinator updates the client using the execution results of each request.
The task execution node resides behind the load balancer, so you can add more nodes as needed to enable horizontal scaling.
Figure 1 shows the logical layer and the flow of information.

Notice how the Task Execution node updates the task Coordin

When using CEF3 as a framework development process, WebSockets, XMLHttpRequest, JS, and local client interactions are required to deliver messages in the render process and in the browse (Browser) session. CEF3 is well encapsulated in this area, and the average user can implement interprocess messaging with only a few interfaces and functions to understand. According to the personal development experience and understanding, take cefclient as an exampl

The OnOpen, OnClose, and OnMessage methods connect events to the socket instance. Each method provides an event to indicate the status of the socket.The OnMessage event provides a data property that can contain the body part of the message. The body part of the message must be a string that can be serialized/deserialized to pass
