HTTP/2 is the new version of the protocol used by the internet to transfer data, HTTP. HTTP (Hypertext Transfer Protocol) is the language or code through which browsers, servers, and other network devices communicate. Since its creation, in 1991, the individual email list message between these elements has evolved and become much more complex, as has the channel, since users access the Internet from devices with different characteristics, such as computers, tablets or smartphones. . To all this we must add that the number of users connected to the Internet has grown significantly in a short period of time, so an evolution of HTTP was necessary.
HTTP/2, then, was born with the intention of solving the problems that arise from a Hypertext Transfer Protocol that is increasingly complicated to respond to increasingly larger and more complex messages or content. Therefore, among many other improvements, we can highlight a higher speed in the transfer of information between the server and the browser. HTTP vs. HTTP/2: main similarities and differences HTTP/2 is born from HTTP, so it keeps the same syntax and also all its main functions . In fact, it's considered more of an update than an entirely new version . But what's new about HTTP/2? One of the novelties is that HTTP/2 is binary instead of textual , so messages are processed much more quickly and efficiently, leaving a very small margin for error. This is because with HTTP there are several ways to interpret the same message, while with HTTP/2 there is only one. Another characteristic is that it is multiplexed and parallel , which allows processing several requests at the same time without one blocking the other. This means that it will not be necessary to bind Js and Css in a single file, since with HTTP/2 it is possible to load several small files at once faster than a single larger file.
