Mar 29, 2018 · WebSockets are a part of the HTML5 spec and they are supported by all modern browsers (meaning, there is a JS API to use them natively in the browser). They provide a mechanism to detect dropped (disconnected) clients and can handle up to a 1024 connections per browser, though they aren’t compatible with most load balancers out-of-the-box and have no re-connection handling mechanism.

HTTP protocol: HTTP is unidirectional where the client sends the request and the server sends the response. WebSocket is a protocol providing full-duplex communication channels over a single TCP connection. Where as, HTTP providing half-duplex communication. Information exchange mode of WebSocket is bidirectional. Means, server can push information to the client (which does not allow direct HTTP). When a WebSocket is typically better than HTTP Just as with HTTP, you’ll find that a WebSocket has its own set of scenarios that illustrate when it may be the best choice for your project. Remember our caution at the start of this blog, however, as the following guidance does not take any special messaging protocol into account.

At this point, XMPP is Websockets have four states: connecting, open, closing and closed. All communication between clients and servers takes place though the use of the websocket frame. A frame is a small, highly bit concerned header + “payload”.

WebSockets maintain a network connection for you (if done right) and listen for changes. Compatibility is one of the major factors for the webpage, for solving compatibility issues, WebSockets uses an HTTP upgrade header to replace HTTP protocol so new HTTP protocol is going to support WebSocket. WebSocket is treated as frame-based where other is considering as stream-based. So it’s treated differently for actual delivery of data.
