The RFC documents and the specifications for new technology published by their creators were used as the main source of information. In the next chapter, the thesis includes a practical test of the new transport protocol SPDY, demonstrating its higher speed. Finally, as a part of this thesis, a simple web chat application based on new technologies using scripting languages PHP and JavaScript, namely WebSocket, Web Storage and IndexedDB, was created.
