About :

In this video, we'll look at WebSockets, a real-time technology that allows a bidirectional connection between a client and a server. We'll start with the basics, explaining what WebSockets are, how they work, and what capabilities they provide. We'll then move on to a practical example, demonstrating how a WebSocket connection works using a group chat. We'll also show you how to intercept a WebSocket connection using Wireshark, and how to test WebSocket applications using Postman.
