Today, I would like to talk to you about how HTTP came out and who created it. Many people may not know much about it. In order to make you understand better, the editor summarized the following content for you. I hope you can get something from this article.

The full name of HTTP protocol is Hypertext transfer Protocol (HypertextTransferProtocol). There are three things to understand: hypertext, transport and protocol. Let's start with the history of HTTP protocol.

In the 1960s, the Advanced Research projects Agency (ARPA) of the US Department of Defense established the ARPA network, which has four nodes distributed all over the world and is considered to be the ancestor of the Internet.

In the 1970s, based on the practice and thinking of ARPA network, researchers invented the famous TCP/IP protocol, and entered the UNIX kernel in the mid-1980s, making more computers connected to the Internet.

The birth of HTTP: Tim Berners Lee (TimBerners-Lee)

Is the founder of the World wide Web, to put it simply, the founder of the contemporary Internet. In 1989, he published a paper on the idea of building a hyperlinked document system on the Internet, in which he identified three key technologies:

URI: uniform resource identifier, as the unique identification of resources on the Internet

HTML: hypertext markup language for describing hypertext documents

HTTP: hypertext transfer protocol, used to transfer hypertext

These three technologies have directly established the technology of our Web world today, which Tim calls the WorldWideWeb.

So, in 1989, HTTP was born.

HTTP/0.9

In the early 1990s, the Internet world was still a desert, with low computer processing power, small storage capacity and slow network speed. Most of the resources on the network are plain text resources, so the HTTP protocol is also in plain text format.

In order to facilitate server and client processing, Tim originally imagined that the documents in the system are read-only, so users are only allowed to obtain HTML documents from the server through GET requests, and immediately close the connection after the response, the function is very limited.

Although this version of HTTP protocol is very simple, but as a prototype, it fully verifies the feasibility of Web services.

HTTP/1.0

In 1993, American national supercomputing Tencent App Center (NCSA) developed Mosaic, which is the first browser that can mix graphics and text, and then developed the server software Apache in 1995, which simplifies the construction of HTTP services.

During the same period, the JPEG image format was invented in 1992 and the MP3 music format was invented in 1995.

The emergence of these new technologies prompted HTTP protocol to add a variety of features, which promoted the development of HTTP protocol from the point of view of user needs.

On the basis of existing practice, after a series of drafts, HTTP/1.0 was officially released in 1996. The following parts are mainly added:

New methods such as HEAD/POST are added.

Added response status code

Added version number

Added the concept of Header header

With the addition of Content-Type, the transmission of data is no longer limited to text

But HTTP/1.0 is not a standard, just a reference document documenting existing practices and patterns, not actually binding, and equivalent to a memo.

After reading the above, do you have any further understanding of how HTTP came out and who created it? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
