What Are Browser Cookies

Cookies are small pieces of information that websites store on your computer. Cookies only contain bits of text, nothing else. The text can be a user ID, session ID, or other text. For example, web pages can be configured, web pages can have hide links that hide certain elements on the page.

This page you are reading may save these settings on your computer with cookies. When you load the page again, the page can check for cookies and automatically hide elements. If you delete cookies, you will be logged out of all websites and the website will not remember any settings you have changed. Cookies are also very common, you may have hundreds or even thousands stored in your browser right now.

Browser Cookies History

Cookies were first developed in 1994 by Lou Montulli, an employee of Netscape Communications. Together with John Giannandrea, Lou developed cookies as a solution to make e-commerce shopping carts possible. The real real-world application of cookies on the web is to determine whether Netscape website visitors have pre-existing.

Initially cookies are accepted by default by all supported browsers and very few end users have any idea of ​​their existence or use. That all changed in February 1996 when the Financial Times published a section detailing its existence, purpose, and use. What followed was intense media scrutiny over the next few years due to the privacy risks inherent in visitor tracking.

The Internet Engineering Task Force (IETF) was tasked with creating an official cookie specification that corresponds to the concerns expressed by the media. Of particular concern are the risks associated with allowing third party cookies. These are better known as tracking cookies. The IETF seeks to request that third party cookies be explicitly prohibited or only permitted after the user has explicitly opted in.

However, the leading browser developers at the time, Netscape and Microsoft, ignored the IETF's recommendations and followed online advertisers' wishes to allow third-party tracking cookies. The current cookie specification acknowledges the use of third party cookies and the risks attached to their use, but ultimately places the responsibility for re-addressing these risks on browser developers:

This document provides user agents (browsers) with broad latitude to experiment with third party cookie policies that balance the privacy and compatibility needs of their users.

How Browser Cookies Work

Your web browser stores and manages cookies. You can find a list of websites that store cookies and view the cookies themselves, although it is usually not interesting to view the content of cookies, in your browser settings. If you use multiple web browsers on your computer, each browser has its own cookies. Websites are only allowed to view their own cookies, for example, when you visit the Technology Monitor website, the Admin cannot check cookies from other websites. This is to prevent malicious websites from snooping and stealing your login session.

Advantages of Cookies

 1. Help websites to “remember” who we are and set preferences accordingly. So that when the user returns to the website, it will be immediately recognized.

 2. Cookies eliminate the need to re-register on the website you visit and when you re-access the website.

 3. Cookies can be useful especially on sites that require registration, so that every time we log in on the site, cookies will create a user login automatically without having to enter the username and password again.

 4. Occupies little memory, does not require server resources and is stored on the user's computer so that there is no additional load on the server.

 5. We can configure cookies to expire when the browser session ends (session cookies) or they can exist for a certain period of time on the client computer (persistent cookies).

 6. Cookies last longer than Session State.

Lack of Cookies

 1. Cookies are not as secure as those stored in text, because they can pose a security risk that allows some people to open and change their cookie settings

 2. Cookies will not work if the security level is set to high in the browser.

 3. User can delete cookies.

 4. User's browser can refuse cookies, so your code should anticipate this possibility.

 5. Complex types of data are not allowed (eg datasets, etc.). It allows only plain text (ie Cookies allows only String content).

 6. Slow down the performance of the web server in loading the website. This is because there are additional javascript scripts and links that point outside the website. It will automatically prolong the website loading process.
