Introduction to what is HTTP, HTTPS, And 301 redirection

September 11

The world of the internet is constantly changing. Many advanced features have been developed, yet many of us are unaware of the basics. Such as have you ever wondered what HTTP or HTTPS is?

This term is often visible on the different address bars of various websites. It is right where you type in the required website that you want to use. So have you ever given it a thought to what it is and what it actually does? If the questions are unanswered, then we are here to guide you to the answers you need.

Let’s begin with the very first lesson. We’ll take it slow to make sure each detail is perfectly understood.

What really is HTTP?

HTTP is the internet’s backbone. HTTP stands for (Hypertext Transfer Protocol), which is a collection of rules for transmitting data over the internet, including text, pictures, sound, video, and other multimedia files. HTTP is indirectly in use as soon as a person opens their web browser.

HTTP is an application protocol that runs on top of the TCP/IP protocol stack, which is the internet’s basics. HTTP/2, which was released in May 2015, is the most recent version of HTTP.

HTTP stands for “Hypertext Transfer Protocol.” The whole World Wide Web is using this protocol. It was established in the early 1990s. Almost all of the information you view in your browser is sent to your computer over HTTP. HTTP headers are the most crucial component of HTTP requests and answers, carrying information about the client browser, the requested page, the server, etc.

At this point, You may be wondering what exactly a client is, especially in this particular subject. A client is a computer or program that relies on sending a request to another program, computer hardware, or software to access a service provided by a server as part of its functioning (which may or may not be located on another computer).

Online browsers like Chrome and Firefox, for example, are clients that connect to web servers and retrieve web pages to display. Email clients access email servers to obtain messages. Online chat employs several clients, which differ depending on the chat protocol.

On each computer, multiplayer video games or online video games may operate as a client. The term “client” also refers to the computers or devices that execute the client software, as well as the individuals that utilize it.

There are five groups or categories for HTTP response status codes. The first digit of the status code determines the answer, but the remaining two numbers have no classification or categorization function.

HTTP Status Codes 

These are a server’s response to a browser’s request. It is known as an HTTP status code. When you visit a website, your browser requests the server, which the server responds to with a three-digit code called the HTTP status code.

To sum this all up, 200s are used for successful requests. While 300s are for redirections, 400s, however, are used if there was a problem with the request. For example, error 403, If you are not allowed to visit a page, this code may be sent to your web browser.

And this mostly happens when you try to open a URL for a folder with no index page. If the server settings do not allow the display of the folder contents, you will get a 403 error. And lastly, continuing with the order, errors with 500s are used if there was a problem with the server.

What is the 301 redirection code?

A 301 redirect is used to redirect from one page to another page The 301 code refers to the HTTP status code of the redirected page. Example: blog.freelance.com has been changed to freelance.com/blog. To put it simply, a 301 redirect tells the browser: “This page has moved permanently. That’s why if you try to visit blog.freelance.com, it won’t work. You’ll eventually end up at freelance.com/blog instead. Click here to create a 301 redirection code to use on your website for redirection from one page to another page.

What is HTTPS?

HTTPS, fully known as hypertext transfer protocol secure, is a different type of HTTP that is extensively used. This implies that the information on a website and the information submitted into it are safe. Most banks, credit card providers, and online retail sites will utilize HTTPS to secure your account or payment information.

 How does HTTPS work?

A secured socket layer (SSL) is used by a website that utilizes HTTPS to encrypt data given on the site or entered into the site. This encryption will keep your information secure and prevent it from falling into the wrong hands.

This aims to keep your information safe while it is in the company’s hands and while it is being transported from the website to the company’s processing facility. When you fill out a form with all of your payment information and click the Next button, the information is transferred over the internet to the company’s processing stations or banks.

During this transfer, data is most likely to be hacked. Companies use HTTPS to keep this information from getting out during this transfer. Most websites will default to this setting on their own, so there is no need for you to change it on your own.

Conclusion

The internet has changed the world’s perception. It has made life easier.  To all the tech newbies out there who are willing to learn web development, may this piece of information help you achieve your goal in the future.
