Perhaps you heard Cookies but don’t know how cookies work? Right.
This all happened due to Cookies files, These questions might need to know how it is possible, how cookies work too. In the following blog, I’ll teach you How Cookies Work? Without labouring to find it.
Are you ready for an excursion into that topic? Let’s get started.
First thing first, I want to let you know all these are happening due to cookies files, stored in our browser while we are browsing. They can also be used to remember what we input the information (names, addresses, passwords) in the form field on websites. Although the website owner can’t access information.
Cookies aren’t what you are thinking of in your mind.
Well, they are intangible files created by websites that you visit rather than food. It makes your online experience easier.
- sites can keep you signed in,
- remember the site preferences
- you’ll get locally relevant content
Additionally, Your browser also opens the website fast as well.
Without cookies, websites would take time to open as when you visit for the first time and take more data too. Hence, Cookies store information from the first session on a website or session of a related website without having to burden a server or website hosting services.
Storing the data on the server without using cookies would also be problematic because it would be difficult to retrieve a particular user’s information without requiring a login on each visit to the website. If you have low data, you would be open a website without delay as well.
How Cookies Work?
You arrive on the main part of the blog — How cookies work? The first time you visit a website (say Life is Aware), the website sends the cookie file to your computer. The PC stores it in a file located inside your web browser.
Whenever you visit Lifeisaware.com again, your browser would send the information contained name-value pairs along with URL in that cookie back to you. Afterwards, Life is Aware Web server receives the cookie data and the request for a page. If no name-value pairs are received, the server finds, you have not visited before.
When you visit some sites, the server gives you a cookie that acts as your I-card, but not hanging on your neck. Upon each return visit to that site, your browser passes that cookie back to the server. In this way, a web server can gather information about which web pages are used the most, and which pages are gathering the most repeat hits. Google Analytics works on the same principle.
Types of cookies:
- First party cookies: They are received from a directly visited website.
- Third-party Cookies: are received from third parties (web servers that haven’t been directly visited). They’re linked to ads on that page. This sort of cookie typically appears when web pages feature content from external websites.
- Session Cookies are temporary cookies deleted when you exit from the browser. It is not used for tracking long information.
Are Cookies bad?
However, some viruses and malware may be disguised as cookies. But your browser handles it. A “zombie cookie” is a cookie that recreates itself after being deleted, it is tough to manage zombie cookies.
Third-party tracking cookies can also cause security concerns since they make it easier for parties you can’t identify to watch where you are going and what you are doing online.
