Protocols in ICT are set of rules that enforce certain manner of communication between different devices to allow them understand each other. HTTP is one of numerous protocols used to transfer information over the Internet and shortly it was designed in purpose of serving websites. 

HTTP version 1.0 or HTTP/1 was documented and published in 1996, followed by improved version 1.1 a year later, in 1997. HTTP/1.1 is still broadly used at present. Work on HHTP/2 was officially finalized in 2015 and the new version delivered number of performance and security improvements.

Version 3 of HTTP introduces substantial changes to the protocol, altering the way of communication towards the manner known from live online applications like video games; maintaining open connection between client and server, and streaming all requested data simultaneously, majorly improving response time and security. While HTTP/3 is neither finalized nor widely available, it was already implemented as a draft and could be used. However it is strongly recommended to allow usage of older versions as HTTP/3 is not yet reliable and could change in the future.
