SgcWebSockets is a complete package providing access to WebSockets protocol, allowing to create WebSockets Servers, Intraweb Clients or WebSocket Clients in VCL, Firemonkey, Linux and FreePascal applications. The WebSocket protocol specification defines ws (WebSocket) and wss (WebSocket Secure) as two new uniform resource identifier (URI) schemes that are used for unencrypted and encrypted connections, respectively. TCP alone deals with streams of bytes with no inherent concept of a message. Unlike HTTP, WebSocket provides full-duplex communication.Additionally, WebSocket enables streams of messages on top of TCP. In this way, a two-way ongoing conversation can take place between the client and the server.

This is made possible by providing a standardized way for the server to send content to the client without being first requested by the client, and allowing messages to be passed back and forth while keeping the connection open. The WebSocket protocol enables interaction between a web browser (or other client application, like VCL Application) and a web server with lower overhead than half-duplex alternatives such as HTTP polling, facilitating real-time data transfer from and to the server.

WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection.
