What is HTTP_2 and what are its advantages?
What is HTTP/2?
HTTP/2 is the new version of the protocol that the Internet uses for data transfer, HTTP.
HTTP (Hypertext Transfer Protocol) is nicaragua email list language or code through which browsers, servers and other network devices communicate. Since its creation in 1991, the 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. In addition to all this, 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 was created with the intention of solving the problems that arise from a Hypertext Transfer Protocol that has increasingly more difficulty responding to messages or content that are increasingly larger and more complex. Therefore, among many other improvements, we can highlight the greater speed in the transfer of information between the server and the browser.
HTTP vs. HTTP/2: Key Similarities and Differences
HTTP/2 is a derivative of HTTP, so it retains the same syntax and all of its core features . In fact, it is considered more of an update than a completely new version . But what's new about HTTP/2?
One of the new features is that HTTP/2 is binary instead of textual , so messages are processed much more quickly and efficiently, leaving very little room 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 feature 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 link Js and Css in a single file, since with HTTP/2 it is possible to load several small files at once more quickly than a single larger file.
We also highlight Server Push , which anticipates the user's request by sending information to the browser before it is requested, which improves loading speed. And finally, header compression , which is able to group and compress headers into a single block to send them as a unit to reduce overhead.
This novelty will be an important digital marketing trend , because it will help in the tracking of the page and make it faster.
