What is a Cookie (Internet)?
I'm sure that more than once when you enter a website you've heard the famous “accept cookies” message, but what exactly are they and what are they for?
Cookies are part of the measurement methods of websites, they are data fragments that are accumulated in a text file on the computers' hard drive.
This video will help explain:
They are generated by web servers, whose mission is to send cookies to different browsers. Once installed, the browsers return the information collected about user behaviour to the servers, making the user see one information or another in their browser.
First, to recognize the user, that is, if someone enters their name and password on a web page, the next time they access the site they will be automatically recognized without having to identify themselves again.
Another use of cookies is to know the behavior of users, that is, to personalize navigation and offer relevant advertising according to the consumer's behavior.
There are different types but we could highlight two classifications:
According to their duration
- Temporary: once the user closes the browser they disappear.
- Permanent: they continue once the browser is closed, and can be set for an unlimited time.
Depending on who manages them
- 1st party (1st part): set by the same domain that appears in your browser.
- 3rd party (3rd part): managed by a third party, normally it is the advertising companies that manage this type of cookies. Their aim is to control user behaviour on various websites.
The first cookie was created by programmer Lou Montulli in 1994, then a developer at Netscape Communications.
The developer's task was to make it possible for e-commerce users to keep the shopping cart filled with the same objects while browsing.
In addition, Montulli had to do this using technology that did not use a lot of server resources. This is why the cookie is a text file installed on the user's computer.
The Origin of Internet Cookies
Once upon a time in the early days of the World Wide Web, a young computer scientist named Lou Montulli sought to answer a burning question: how could websites remember their visitors? Montulli, an ingenious mind at Netscape Communications Corporation in 1994, embarked on a quest to create a more personalized and seamless browsing experience for web users.
The term “cookie” was borrowed from the magical world of “magic cookies,” which referred to small data tokens exchanged between programs to maintain state information.
Montulli, in his infinite wisdom, applied this concept to the web, giving birth to the humble internet cookie. This little text-based data packet allowed web servers to send snippets of information to users' browsers, which would then be stored on their computers. Like breadcrumbs left behind, the cookies could be sent back to the server each time the user revisited a site, enabling it to remember preferences and activities.
As the tale of the internet cookie spread, it became a staple ingredient in the very first version of the Netscape Navigator browser. This small but mighty innovation sparked a revolution in the evolution of the web, paving the way for interactive and customizable online experiences.
Early adopters of cookies delighted in the convenience of stored login information, preserved shopping cart contents, and remembered user preferences, like language and font size.
In the years that followed, cookies expanded their reach far beyond their initial intent. They became the secret sauce of countless websites, enabling advanced features like user authentication and personalized content delivery. The enchanting world of internet cookies eventually gained a formal spellbook in December 1996, known as “HTTP State Management Mechanism” or RFC 2109.
This spellbook was later replaced by RFC 2965 in October 2000 and ultimately by RFC 6265 in April 2011, as the guidelines for conjuring and managing cookies continued to evolve.
From their humble beginnings as Montulli's brainchild, internet cookies have flourished into an indispensable part of our online experiences.
While the growing concerns around privacy and data security have led to stricter rules and a heightened focus on user consent, cookies remain the lifeblood of the modern web, enchanting us with their ability to make our digital lives more seamless and enjoyable.
What are the Types of Internet Cookies?
In the vast digital landscape, internet cookies come in various flavors, each serving a unique purpose in enhancing our browsing experience. These small text files, stored on our computers, help websites remember our preferences, track our activities, and provide a personalized experience. Let's delve into the different types of cookies and their distinct roles in shaping our online interactions.
1. Session cookies: Also known as transient or temporary cookies, session cookies are short-lived, remaining active only during a single browsing session. They help websites remember your actions and selections, such as items in your shopping cart or your navigation history. Once you close the browser, session cookies vanish, ensuring that your browsing data remains private and secure.
2. Persistent cookies: Unlike their transient counterparts, persistent cookies have a longer lifespan, typically lasting from days to years. They store user preferences and settings for future visits, enabling websites to remember your login credentials, preferred language, or display settings. The cookie's lifespan is determined by a predetermined expiration date set by the website or can be manually deleted by the user.
3. Third-party cookies: Created and managed by domains other than the one you are currently visiting, third-party cookies facilitate cross-site tracking and advertising. These cookies enable advertisers to gather information about your browsing habits, tailor ads to your interests, and measure ad effectiveness. Due to privacy concerns, third-party cookies are facing increased scrutiny and are being phased out or blocked by some browsers and privacy-focused tools.
4. Secure cookies: As the name suggests, secure cookies prioritize data protection, transmitting information exclusively over HTTPS connections. This ensures that the cookie's data is encrypted, safeguarding it from interception or manipulation by malicious parties. Secure cookies are essential for protecting sensitive user data, particularly on websites that handle financial transactions or personal information.
5. HttpOnly cookies: Developed to combat cross-site scripting (XSS) attacks, HttpOnly cookies cannot be accessed by client-side scripts such as JavaScript. This restriction limits the potential for attackers to steal or manipulate cookie data, bolstering the overall security of your browsing experience.
6. SameSite cookies: Designed to prevent cross-site request forgery (CSRF) attacks, SameSite cookies dictate whether a cookie should be sent with cross-origin requests. With three attribute values (Strict, Lax, and None), SameSite cookies allow web developers to control the degree of restriction, enhancing the security and privacy of user data.
7. Zombie cookies: Dubbed “zombie” for their ability to resurrect after deletion, these cookies utilize multiple storage mechanisms, such as Flash Local Shared Objects (LSOs) or IndexedDB, to persistently store user data. Often considered invasive, zombie cookies pose privacy concerns and are generally frowned upon in the digital community.
Each type of internet cookie plays a distinct role in our online experiences, with some focusing on enhancing usability and others prioritizing security or enabling targeted advertising. As users become more conscious of their digital privacy, it is crucial to understand the various cookies at play and manage them accordingly.
As the web continues to evolve, new types of cookies or alternative tracking methods may emerge. However, understanding the current landscape of internet cookies enables us to make informed decisions about our online privacy and helps us strike a balance between convenience and security in our digital lives.
How Internet Cookies Work?
Internet cookies are ingenious little tools that play a significant role in shaping our online experiences. These small text files, stored on our devices, help websites remember our preferences, track our activities, and deliver personalized content. But how exactly do these cookies work their magic? Let's explore the inner workings of internet cookies and their interaction with our browsers.
Creating and storing cookies: The process begins when you visit a website for the first time. The web server generates a unique cookie, which contains a string of text, and sends it to your browser. This string often includes an identification number, an expiration date, and other data relevant to your browsing session. Your browser then stores the cookie on your device, usually in a dedicated folder, for future use.
Browser interaction with cookies: When you revisit the same website, your browser retrieves the stored cookie and sends it back to the web server. This exchange allows the server to recognize you as a returning visitor, recall your preferences, and customize your browsing experience accordingly. For example, a cookie might remember your preferred language or the items you added to your shopping cart during your last visit.
Depending on their type and purpose, cookies may store a wide range of information, from login credentials and site settings to browsing history and behavioral data. Session cookies, for instance, only last for a single browsing session and store temporary data, while persistent cookies remain on your device for a longer period and remember your preferences across multiple sessions.
Managing and deleting cookies: Although cookies are essential for many websites to function correctly, users have the option to manage them as needed. Most browsers allow you to control cookie storage, delete existing cookies, or even block them entirely. However, it's essential to understand that restricting or removing cookies may impact your browsing experience, causing some websites to function suboptimally or lose personalization features.
In summary, internet cookies work by storing small bits of text on your device, which are then used by web servers to recognize you as a returning visitor and tailor your browsing experience.
Cookies are created and managed through a seamless interaction between your browser and the web server, making your online journeys more enjoyable and efficient. While it is essential to be mindful of the potential privacy concerns associated with cookie usage, understanding their inner workings helps us strike a balance between convenience and digital security.
