Възможности за използване на протокол HTTP/2 за намаляване на лага при зареждане на уеб приложения

This article examines the evolution of the protocol HTTP - from version 0.9 through 1.0, and 1.1 to version 2. The factors affecting latency and lag when loading web pages are discussed in details. The research concludes that nowadays network bandwidth plays an increasingly small role about the lag. The results of empirical research how much the lag is reduced when using HTTP/2 while loading an average by volume and by content web page are presented. In the tests are used different versions of the protocol HTTP - HTTP/1.0, HTTP/1.1, HTTPS/1.1 and HTTPS/2. An experimental software is created and an external program to simulate network latency is used.
