WebSocket is a protocol that allows you to send files, apps, or data via the Internet. This protocol has three components: structure, functions and security. In addition, it supports extensions and enables you to use your own data formats. These features are available to learn more.
Structure
WebSocket is a protocol which allows applications to send and receive messages through another application. It is an overlay on the TCP/UDP traditional transport layer protocol. In addition, the protocol enables message retry and disconnection. It sends two types, the control and the connection messages.
The connection data are framed with the payload specified by the application. Each frame also contains the payload data. However, the base WebSocket specification does not support data compression, so applications must implement their own data compression logic. Data compression extensions provide the equivalent to HTTP's transfer-encoding negotiation. These extensions may be advertised in Upgrade handshake. The server can then select them for the duration of the connection.
Functions
Websocket lets you send and retrieve messages from a remote server. To send a message you must first create the socket connection within your application. Then, you must create an event listener that will be called whenever a new message arrives on the server. You can then respond to the message using the WebSocket service.
WebSocket allows you to send and receive data from two devices. It allows client and server to simultaneously exchange messages. WebSockets are particularly useful when fetching data from servers. This is not possible via 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 of the WebSocket protocol that inspects WebSocket connection and protects data being transmitted through them. WebSocket security can be enabled or disabled for a Web application 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. Also, the browser automatically adds its cookies the WebSocket handshake request. This means that attackers have access to victim's credentials.
WebSocket security implementation is very simple and can be completed in just a few steps. First, verify the "Origin" header of the websocket connection. If the header does not match, the WebSocket connection will be closed. Second, verify that the message's frames are correct. Third, ensure that the connection is made via an SSL channel. Information can leak and other attacks can occur if it is not.
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 extensions are activated by the server and returned to the client.
The websocket extension library is used to implement websocket extensions. This library is independent from the main protocol and defines abstractions of messages and frames. It also implements a number of APIs that enable plugins and drivers to interoperate.
