One of the elements that make up the connection network is the HTTP protocol, as it establishes the same language that allows compression between the request made by the client and the Internet content.

Navigation is a complex network that allows the exchange of data via computer, where protocols set the standard for ordering and facilitating transmission. All this happens through the World Wide Web, which is nothing more than a set of pages, domains and servers in charge of managing information.



This protocol arises from the need for facilitate the way this data was distributed across the network, so as not to cause inconvenience or displeasure to users who search within a browser.

Its launch dates back to 1999, based on an idea that had the World Wide Web Consortium, also receiving the collaboration of the Internet Engineering Task Force. Because it is a very necessary aspect, defining it and explaining how it works is something we will focus on in this article.

How could you define the HTTP protocol?

The initials that make up its name are the initials of HyperText Transfer Protocol, which means nothing but "Hypertext Transfer Protocol".

As the name indicates, it is a server that takes care of the error-free data transmission, which is enabled whenever a client (user and browser program) makes a request over the Internet.

Within the navigation platform, the HTTP protocol acts as code that allows both computers to understand each other, and therefore to be able to process the information to be transmitted. This coding consists of a series of criteria that establish the form and meaning of the syntax that makes up the protocol itself, thus realizing the communication.



Likewise, it manages to establish the guidelines that customer requests must follow in order to generate successful results.

HTTP protocol performance method

So far we have implied the sequences of this protocol they work in a request and response order, established between two computers, where one represents the client and the other the web server that owns the content.

In this way a mutual communication is formed, with the aim of marking a beginning, a development and a closure of the data transmission between them.

A very simple example is when you decide to open your favorite web page, the procedure of which involves a sequence of opening the browser, entering the URL and pressing "Enter".

From this point on, the explorer program starts communicating with the server where the requested information is hosted.

Said server, on the other hand, will have the task of establish the methods of transmission of the information to be sent: the position of the text, images and other content.

This is how a code exchange is created through the protocol, which translates into the representation of the requested information on your computer screen.


What is the HTTPS protocol about?

This is nothing more than an extension of the HTTP protocol, except that it comes through it established a secure connection for data exchange.

That is, it is a variable responsible for forming a space, protected by encryption, to transmit sensitive information. One example is passwords.

Its creation was based on the fact that, through the usual protocol, any third party is able to access the data that is exchanged between client and server. Therefore, to avoid this type of circumstance, HTTPS creates a series of "layers" in the network that can only be decrypted between the transmitting computers.


Currently, it is the most recommended version for users, since prevents information theft and invasion of privacy, which is very common within platforms and Internet pages.
