HTTP and Cookies
What is a Cookie?
See, it is not the one that you eat but it is the one which is saved on a user’s browser.

Yes! You heard it right.

It is a small piece of data that is sent from a website and stored on the user's i.e. your computer by your browser while browsing.
Cookies were specially designed for this purpose and are to a reliable mechanism for websites to remember how users browse on a particular website, what are there interest areas, etc. so as to serve a user better next time.

With the help of HTTP Cookies, we can exchange information between the server and the browser so as to customize a user session, and for servers to recognize the user between requests.

These are special messages that web servers pass to your web browser while visiting any website. The messages are stored by the browser in a small file, called cookie.txtWhen another page is requested from the server, the cookie is sent back to the server.
Let’s take an example:
You must have often noticed that when you visit any website 2nd time, you already have content displayed according to your needs but this was not the case for the 1st time. Almost every website has cookies enabled in it.

The most common example which we use in our day-to-day life in which content is optimized according to Cookies is YouTube. The videos are displayed according to our history. It means the HTTP cookies are saved in our devices according to the way we search and watch videos on the YouTube app or on the YouTube website.
This information saved by the browser in the desktop computer and by the app in mobile are transferred to the website and hence, our preferences are set according to that.

Let us now have a look at the process of enabling Cookies on Browser.

These were the methods to enable and disable Cookies in Google Chrome, Mozilla Firefox, Internet Explorer and Opera. You must be wondering that if the Cookies are able to trace our activities on the website, then is it not a threat to our privacy?

No, Not at all !!!
It is because - Only that website which creates a cookie can read it, and hence, other servers do not have access to your information. Additionally, Web servers can use only the information that you provide or the choices that you make while visiting the website
as content in cookies.

It means enabling Cookies on your Browser is safe and secure and hence, no threat to your privacy. So, this was all about Cookies. As it is not a very vast topic, We have carefully compiled the information so that you can get the best understanding.
