WebSocket is a computer, providing communication channels over a single connection. The WebSocket protocol was standardized by the as 6455 in 2011, and the WebSocket in is being standardized by the. Descargar musica karaoke gratis. WebSocket is a different protocol from HTTP. Both protocols are located at layer 7 in the and, as such, depend on TCP at layer 4. Although they are different, states that WebSocket 'is designed to work over HTTP ports 80 and 443 as well as to support HTTP proxies and intermediaries' thus making it compatible with the HTTP protocol. To achieve compatibility, the WebSocket uses the to change from the HTTP protocol to the WebSocket protocol.

The WebSocket protocol enables interaction between a (or other client application) and a with lower overheads, facilitating real-time data transfer from and to the server. This is made possible by providing a standardized way for the server to send content to the client without being first requested by the client, and allowing messages to be passed back and forth while keeping the connection open. In this way, a two-way ongoing conversation can take place between the client and the server. The communications are done over TCP number 80 (or 443 in the case of -encrypted connections), which is of benefit for those environments which block non-web Internet connections using a. Similar two-way browser-server communications have been achieved in non-standardized ways using stopgap technologies such as. Most browsers support the protocol, including,,,,.
