WebSockets

📄️ Websockets Support For Java

The WebSocket protocol was implemented to replace the existing bi-directional communication mechanisms that uses HTTP as a transport layer, as HTTP was not initially meant to be used for these purposes. This new technology ensures establishment of a single full-duplex TCP connection between client and server, where messages are instantly transmitted with little overhead, both upstream and downstream at once. At the same time, WebSockets technology is designed to work over the standard HTTP ports (80 and 443) and to support HTTP proxies and intermediaries, representing a trade-off between efficiency and reliability

WebSockets is a widely spread client-server technology, which allows you to implement the instant messages exchanging within your application. This is achieved through establishing the continuous full-duplex TCP-based connection between server and client’s browser. Using such communication channels results in a very low connection latency and rapid interaction, simultaneously ensuring streaming through proxies and firewalls, both upstream and downstream at once.
