WebSocket can be used to send data, files, and applications over the Internet. The protocol is composed of a structure, functions, security, and security. It supports extensions and allows you to create your own data formats. These features can be learned more.
Structure
WebSocket enables applications to send or receive messages from other applications. It is layer on top of TCP/UDP, the transport layer protocols. In addition, the protocol enables message retry 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 does not support data compressing, so applications need to implement their data compression logic. Data compression extensions enable the equivalent of transfer-encoding negotiation found in HTTP. These extensions can also be advertised via the Upgrade handshake.
Functions
Websocket functions let you send and receive messages from a 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. Next, you will be able to use the WebSocket functionality to respond to that message.
WebSocket is used for data exchange 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 not possible through HTTP requests. WebSocket is used to send the request to the server. It will first check the order, then process it.
Security
WebSocket protection is an extension to WebSocket protocol. This inspects WebSocket connectivity and secures data transferred through them. WebSocket security may be disabled for a Webapplication or website. When enabled, a default WebSocket profile is created for a web application or website. This profile has a status of OFF, which means that the service is not active. The browser adds cookies to the WebSocket handshake requests automatically, meaning that attackers have access.
WebSocket security has a simple implementation and can be achieved in just a few short steps. First, verify the "Origin" header of the websocket connection. The WebSocket connection can be terminated if the header is not correct. Second, verify that the message's frames are correct. Third, be sure to verify that the connection is using an SSL channel. You could be vulnerable to other attacks and information may leak.
Extensions
Websocket extensions can be described as a list of parameters returned from the server 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 may be implemented with the websocket–extensions libraries. 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.
