When you want to send a file, application, or data across the Internet, you can use the WebSocket protocol. This protocol has many components, including a structure, security, and functions. It supports extensions and allows you to create your own data formats. These features can be learned more.
Structure
WebSocket allows an application to send and get messages from another application. It is built on top the TCP/UDP transport layer protocols. In addition, the protocol enables message retry and disconnection. It can handle two types of messages: the control and connection message.
The payload is the connection data, which is framed with application payload. Each frame also contains payload information. The WebSocket base specification doesn't support data compression. Applications must implement their data compression logic. Data compression extensions enable the equivalent of transfer-encoding negotiation found in HTTP. These extensions can be advertised in the Upgrade handshake, and the server can select them for the life of the connection.
Functions
Websocket lets you send and retrieve messages from a remote server. First, create a socket in your application. Next, create an event listener to be called when a new message arrives at the server. You can then use the WebSocket function in order to reply to the message.
WebSocket is used for data exchange between two devices. It allows the client to send and receive data simultaneously from both servers. WebSockets are especially useful for retrieving data from servers. This is not possible with HTTP requests. The server will have to check the order and then process the request, but it will do so through WebSocket.
Security
WebSocket security is an extension to the WebSocket protocol which inspects WebSocket connections and secures the data that is transferred through them. WebSocket security can be enabled or disabled for a Web application or website. A default WebSocket profile for a website or web application is created when enabled. This profile has a status code of OFF which indicates that the service is inactive. Also, the browser adds its cookies automatically to the WebSocket Handshake Request. This indicates that the attacker has access the victim's credentials.
WebSocket security can be implemented in a few easy steps. First, check the header "Origin" of the websocket connection. The WebSocket will close the connection if the header doesn't match. Also, make sure you check the message's format. Third, ensure that the connection is made via an SSL channel. Otherwise, information could leak out and other attack vectors may occur.
Extensions
Websocket extension are parameters returned by 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 is responsible for activating the extensions and returning them to the client.
The websocket extension library is used to implement websocket extensions. This library is separate from main protocol. It defines abstractions to messages and frames. It also implements a number of APIs that enable plugins and drivers to interoperate.
