When a large amount of data distributed from a Web server, delivery delay may occur in other data depending on the network environment. In this research, we construct a synchronous mechanism that can distribute the data to the clients based on defined priority using HTTP/2. We extend the priority control function of HTTP/2 to define priority for each data to be synchronized. The application developers can assign a priority on the request header when the data is distributed from the browser.
