Network communication system and method with web push protocol
A communication system includes a Remote Proxy device and an Edge Proxy device. The Remote Proxy receives a request for a website from a user terminal, and transmits the request to the Edge Proxy via satellite. The Edge Proxy receives the request and transmits the request to a Web Server over a high speed connection. The Edge Proxy receives the response from the Web Server, and transmits the response to the Remote Proxy via satellite, which then transmits the response to the User Terminal. The Edge Proxy also reviews the response and requests objects for the website from the Web Server, and transmits the objects to the Remote Proxy, which then transmits it to the User Terminal.
