How do we create a WebSocket in HTML?
Following is the API which creates a new WebSocket object. var Socket = new WebSocket(url, [protocal] ); Here first argument, url, specifies the URL to which to connect. The second attribute, protocol is optional, and if present, specifies a sub-protocol that the server must support for the connection to be successful.
What are Web sockets used for?
The WebSocket protocol enables interaction between a web browser (or other client application) and a web server with lower overhead than half-duplex alternatives such as HTTP polling, facilitating real-time data transfer from and to the server.
What is WebSocket programming?
The WebSocket API is an advanced technology that makes it possible to open a two-way interactive communication session between the user’s browser and a server. With this API, you can send messages to a server and receive event-driven responses without having to poll the server for a reply.
What is WebSocket in Java?
WebSocket is an application protocol that provides full-duplex communications between two peers over the TCP protocol. In the traditional request-response model used in HTTP, the client requests resources, and the server provides responses.
How does a WebSocket work?
WebSocket uses HTTP as the initial transport mechanism, but keeps the TCP connection alive after the HTTP response is received so that it can be used for sending messages between client and server. WebSockets allow us to build “real-time” applications without the use of long-polling.
What is WebSocket programming in Java?
What is Web technology socket?
A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to.
Can WebSocket replace HTTP?
There is no harm if you support both models. Use REST for one way communication/simple requests & WebSocket for two way communication especially when server want to send real time notification. WebSocket is a more efficient protocol than RESTful HTTP but still RESTful HTTP scores over WebSocket in below areas.
