Internet development requires the development of protocols to be in line with contemporary needs. Nevertheless, HTTP, being one of the most popular protocols, had not been updated during a very long time (15 years, to be precise!).
The new version of the protocol was released in May of 2014, and in September 1, 2018, W3Techs found out that 29.6% of the top 10 million websites support HTTP/2.
In this report we will discuss what changes have been made in comparison with the old version, see in detail how HTTP/2 works inside and what attacks it is already immune to.
