WebSocket allows you to send files or applications across the Internet. This protocol has several components: a structure, functions, and security. It also supports extensions, and lets you use your data formats. Find out more about these features.
Structure
WebSocket enables applications to send or receive messages from other applications. It is built on top the TCP/UDP transport layer protocols. In addition, the protocol enables message retry and disconnection. It uses two types of messages, namely the connection and the control message.
The connection data is framed with the payload provided by the application, and each frame carries payload data. The WebSocket base specification doesn't support data compression. Applications must implement their data compression logic. Data compression extensions are the equivalent to HTTP transfer-encoding negotiations. These extensions are advertised in the Upgrade Handshake. Servers can choose to use them for the entire life of the connection.
Functions
Websocket lets you send and retrieve messages from a remote server. First, create a socket connection in your application to send a message. Then, you must create an event listener that will be called whenever a new message arrives on 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 both the client and server to send and receive messages simultaneously. A WebSocket is particularly useful for fetching data from a server. This is not possible using HTTP requests. WebSocket will allow the server to verify the order and process the request.
Security
WebSocket encryption is an extension for the WebSocket protocols that inspects WebSocket networks and secures data sent through them. WebSocket security can be enabled or disabled for a Web application or website. WebSocket security can be enabled to create a default profile for a Web app or website. This profile has a status code of OFF which indicates that the service is inactive. The browser adds cookies to the WebSocket handshake requests automatically, meaning that attackers have access.
Fortunately, WebSocket security is relatively simple to implement and can be done in just a few simple steps. First, verify the "Origin" header of the websocket connection. The WebSocket connection is closed if it doesn't match. Also, make sure you check the message's format. Third, verify that the connection takes place over SSL channel. You could be vulnerable to other attacks and information may leak.
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 server activates the extensions and returns them to the client.
Websocket extensions can be implemented using the websocket–extensions library. This library is separate from main protocol. It defines abstractions to messages and frames. It also implements APIs that allow drivers and plugins to interact.
FAQ
