WebSocket can be used to send data, files, and applications over the Internet. The protocol is composed of a structure, functions, security, and security. You can also use extensions and your own data formats. These features can be learned more.
Structure
WebSocket enables applications to send or receive messages from other applications. It is added to the TCP and UDP transport layer protocols. The protocol also allows message retrying and disconnection. It works with two types message, the control message as well as the connection.
The connection data frames the payload of the application and each frame contains payload. WebSocket's base specification does not support data compression. Therefore, applications must create their own data compression logic. Data compression extensions allow for the equivalent of HTTP transfer-encoding negotiation. These extensions can be listed in the Upgrade handshake and can be selected by the server for the lifetime of the connection.
Functions
Websocket functions enable you to send or receive messages from a web server. First, create a socket connection in your application to send a message. Next, create an event listener to be called when a new message arrives at the server. Then, you can use the WebSocket function to respond to the message.
WebSocket is used to send and receive data between two devices. It allows the client and the server to exchange messages simultaneously. WebSockets are especially useful for retrieving data from servers. This is impossible with HTTP requests. WebSocket is used to send the request to the server. It will first check the order, then process it.
Security
WebSocket security extends the WebSocket protocol. It inspects WebSocket connections to ensure that data is not being transferred over them. WebSocket security can either be disabled or enabled for a Web app or website. If enabled, a default WebSocket Profile is created for a Web application or website. This profile has a status OFF, meaning that the service's inactive. The browser adds cookies to the WebSocket handshake requests automatically, meaning that attackers have access.
WebSocket security implementation is very simple and can be completed in just a few steps. First, verify that the "Origin” header on the websocket connections matches. If the header is not identical, the WebSocket connections will be closed. Second, be sure to check the message's frame format. Third, verify that the connection takes place over SSL channel. Otherwise, information could leak out and other attack vectors may occur.
Extensions
Websocket extensions refer to a set parameters that the server returns to the client. These are specified in the "Sec-WebSocket-Extensions" header and must be implemented by both the client and the server. The extension activation and return to client is the responsibility of the server.
Websocket extensions can be implemented using the websocket–extensions library. This library is independent from the main protocol and defines abstractions of messages and frames. It implements a variety of APIs which enable drivers and plugins interoperate.
