BitTorrent is a peer-to-peer file sharing (P2P) communications protocol. It is a method of distributing large amounts of data widely without the original distributor incurring the entire costs of hardware, hosting and bandwidth resources. The protocol was designed in April 2001, implemented and first released 2 July 2001 by programmer Bram Cohen, and is now maintained by BitTorrent, Inc. It identifies content by URL and is designed to integrate seamlessly with the Web.

sgcWebSockets is a complete package providing access to WebSockets protocol, allowing to create WebSockets Servers, Intraweb Clients or WebSocket Clients in VCL, Lazarus/FPC and Firemonkey applications. WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. The WebSocket protocol was standardized by the IETF as RFC 6455 in 2011. WebSocket is designed to be implemented in web browsers and web servers, but it can be used by any client or server application. The WebSocket protocol makes possible more interaction between a browser and a web site, facilitating live content and the creation of real-time game.
