When you want to send a file, application, or data across the Internet, you can use the WebSocket protocol. This protocol has three components: structure, functions and security. It supports extensions and allows you to create your own data formats. These features are available to learn more.
Structure
WebSocket allows an application to send and get messages from another application. It is layered on top of the traditional transport layer protocols TCP and UDP. The protocol also allows message retrying and disconnection. It utilizes two types messages: the control message and the connection message.
The payload is the connection data, which is framed with application payload. Each frame also contains payload information. Data compression is not supported by the WebSocket standard, so applications will need to implement their own data compression logic. Data compression extensions provide the equivalent to HTTP's transfer-encoding negotiation. These extensions can also be advertised via the Upgrade handshake.
Functions
Websocket functions let you send and receive messages from a server. To send a message you must first create the socket connection within your application. After that, you will need to create an "event listener" that will be called whenever there is a new mail on the server. You can then use the WebSocket function in order to reply to the message.
WebSocket allows you to send and receive data from two devices. It allows clients and servers to simultaneously exchange messages. WebSockets can be used to fetch data from a server. This is impossible with HTTP requests. WebSocket will enable the server to validate the order and process the request.
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 either be disabled or enabled for a Web app or website. Enabled creates a default WebSocket profile that can be used for any website or web app. 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 has a simple implementation and can be achieved in just a few short steps. First, verify the "Origin" header of the websocket connection. If the header does not match, the WebSocket connection will be closed. Also, make sure you check the message's format. Make sure the connection is over SSL channels. Without SSL, information can leak and other attack vectors could occur.
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 extension activation and return to client is the responsibility of the server.
Websocket extensions are implemented using the websocket-extensions library. This library is separate to the main protocol. It defines abstractions and frames for messages and frames. It implements several APIs that allow plugins and drivers interoperate.

This makes them great for mobile users.
Desktop Applications
Desktop applications may have more advanced features than cloud-based solutions but they aren’t always necessary. Some people prefer to work exclusively from a desktop app because they find it more convenient. Some prefer to use the exact same tool whether they're using a smartphone or a laptop.
