Dart: Scalable Application Development

WebSocket

WebSocket is a bidirectional, message-oriented streaming transport between a client and a server. It is a built in TCP that uses an HTTP upgrade handshake. WebSocket is a message-based transport. Its simple and minimal API abstracts all the complexity and provides the following extra services for free:

• The same-origin policy enforcement
• Interoperability with the existing HTTP infrastructure
• Message-oriented communication
• Availability of subprotocol negotiation
• Low-cost extensibility

WebSocket is one of the most flexible transports available in the browser. The API enables the layer and delivers arbitrary application protocols between the client and server in a streaming fashion, and it can be initiated on either side at any time.
