WebSocket can be used to send data, files, and applications over the Internet. This protocol has many components, including a structure, security, and functions. It also supports extensions, and lets you use your data formats. Learn more about these features.
Structure
WebSocket lets an application send and receive messages to another application. It is layer on top of TCP/UDP, the transport layer protocols. The protocol also allows message retrying and disconnection. It uses two types of messages, namely the connection and the control 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 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 allows you to send and receive messages from servers. To send a Message, first you need to create a socket connection. 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 lets you send and get data between two computers. It allows the client and the server to exchange messages simultaneously. WebSockets are especially useful for retrieving data from servers. This is not possible via HTTP requests. WebSocket allows the server to process the request through WebSocket.
Security
WebSocket protection is an extension to WebSocket protocol. This inspects WebSocket connectivity and secures data transferred through them. WebSocket security is configurable for Web applications and websites. If enabled, a default WebSocket Profile is created for a Web application or website. This profile has a status code of OFF which indicates that the service is inactive. The browser adds automatically its cookies to the WebSocket request. This gives the attacker access to the victim’s credentials.
WebSocket security implementation is very simple and can be completed in just a few steps. First, verify that the "Origin” header on the websocket connections matches. The WebSocket connection is closed if it doesn't match. Second, be sure to check the message's frame format. Third, ensure that the connection is made via an SSL channel. Without SSL, information can leak and other attack vectors could 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 to activate the extensions and return them to clients.
Websocket extensions are implemented using the websocket-extensions library. This library is independent from the main protocol and defines abstractions of messages and frames. It also implements many APIs, which allow plugins or drivers to interoperate.
FAQ
