What is a cookie?

What is a Cookie? A cookie is often used to identify a user. A cookie is a small file that the server embeds on the user's computer. Each time the same computer requests a page with a browser, it will send the cookie too. HTTP/ OK Content-type: text/html Set-Cookie: cookie_name1=cookie_value1 Set-Cookie: cookie_name2=cookie_value2; expires=Sun, GMT [content of the page here] The client sends back to the server its cookies previously stored. Definition - What does HTML5 Cookie mean? An HTML 5 cookie is a cookie-like storage options available in HTML 5. It consists of browser-based local storage and session storage, which is created and accessible by the Web page itself. An HTML5 cookie is also known as HTML5 Web storage and is an alternative to the commonly used browser cookie. An HTTP cookie (web cookie, browser cookie) is a small piece of data that a server sends to the user's web browser. The browser may store it and send it back with later requests to the same server. Typically, it's used to tell if two requests came from the same browser — keeping a user logged-in, for example. Cookies, or, to give them their formal name, HTTP cookies, are text files made up of tiny bits of data, which are stored on a web browser. These tiny bits of data are used by websites to track a user’s journey, enabling them to offer features that are specific to each individual user. Because of this, cookies are at the heart of a website’s functionality.

These are mainly used for advertising and tracking across the web. See for example the types of cookies used by Google. A third party server can build up a profile of a user's browsing history and habits based on cookies sent to it by the same browser when accessing multiple sites.

Firefox, by default, blocks third-party cookies that are known to contain trackers. Third-party cookies or just tracking cookies may also be blocked by other browser settings or extensions.

Cookie blocking can cause some third-party components such as social media widgets to not function as intended. These regulations have global reach, because they apply to any site on the World Wide Web that is accessed by users from these jurisdictions the EU and California, with the caveat that California's law applies only to entities with gross revenue over 25 million USD, among other things.

There may be other regulations governing the use of cookies in your locality. The burden is on you to know and comply with these regulations.

There are companies that offer "cookie banner" code that helps you comply with these regulations. The window. Other techniques have been created to cause cookies to be recreated after they are deleted, known as "zombie" cookies.

However, they are also used for "legitimate" reasons such as keeping users logged into their accounts on websites, to avoid re-entering login credentials at every visit.

A secure cookie can only be transmitted over an encrypted connection i. They cannot be transmitted over unencrypted connections i.

This makes the cookie less likely to be exposed to cookie theft via eavesdropping. A cookie is made secure by adding the Secure flag to the cookie.

This restriction eliminates the threat of cookie theft via cross-site scripting XSS. A cookie is given this characteristic by adding the HttpOnly flag to the cookie.

In Google Chrome version 51 introduced [21] a new kind of cookie with attribute SameSite. This would effectively mitigate cross-site request forgery CSRF attacks.

Chrome, Firefox, Microsoft Edge all started to support Same-site cookies. Normally, a cookie's domain attribute will match the domain that is shown in the web browser's address bar.

This is called a first-party cookie. A third-party cookie , however, belongs to a domain different from the one shown in the address bar.

This sort of cookie typically appears when web pages feature content from external websites, such as banner advertisements. This opens up the potential for tracking the user's browsing history and is often used by advertisers in an effort to serve relevant advertisements to each user.

As an example, suppose a user visits www. This website contains an advertisement from ad. Then, the user visits another website, www.

Eventually, both of these cookies will be sent to the advertiser when loading their advertisements or visiting their website.

The advertiser can then use these cookies to build up a browsing history of the user across all the websites that have ads from this advertiser, through the use of the HTTP referer header field.

As of [update] , some websites were setting cookies readable for over third-party domains. Most modern web browsers contain privacy settings that can block third-party cookies.

Google Chrome introduced new features to block third-party cookies. Henceforth, they are now blocked by default in Incognito mode, while a user can choose to block them in the normal browsing mode too.

The update also added an option to block first-party cookie too. Some browsers block third-party cookies. As of July , Apple Safari , [30] Firefox , [31] and Brave , [32] block all third-party cookies by default.

Safari allows embedded sites to use Storage Access API to request permission to set first-party cookies. Chrome plans to start blocking third-party cookies by A supercookie is a cookie with an origin of a top-level domain such as.

Ordinary cookies, by contrast, have an origin of a specific domain name, such as example. Supercookies can be a potential security concern and are therefore often blocked by web browsers.

If unblocked by the browser, an attacker in control of a malicious website could set a supercookie and potentially disrupt or impersonate legitimate user requests to another website that shares the same top-level domain or public suffix as the malicious website.

For example, a supercookie with an origin of. This can be used to fake logins or change user information. The Public Suffix List [34] helps to mitigate the risk that supercookies pose.

The Public Suffix List is a cross-vendor initiative that aims to provide an accurate and up-to-date list of domain name suffixes.

Older versions of browsers may not have an up-to-date list, and will therefore be vulnerable to supercookies from certain domains. The term "supercookie" is sometimes used for tracking technologies that do not rely on HTTP cookies.

Two such "supercookie" mechanisms were found on Microsoft websites in August cookie syncing that respawned MUID machine unique identifier cookies, and ETag cookies.

A zombie cookie is a cookie that is automatically recreated after being deleted. This is accomplished by storing the cookie's content in multiple locations, such as Flash Local shared object , HTML5 Web storage , and other client-side and even server-side locations.

To keep track of which user is assigned to which shopping cart, the server sends a cookie to the client that contains a unique session identifier typically, a long string of random letters and numbers.

Because cookies are sent to the server with every request the client makes, that session identifier will be sent back to the server every time the user visits a new page on the website, which lets the server know which shopping cart to display to the user.

Another popular use of cookies is for logging into websites. When the user visits a website's login page, the web server typically sends the client a cookie containing a unique session identifier.

When the user successfully logs in, the server remembers that that particular session identifier has been authenticated and grants the user access to its services.

Because session cookies only contain a unique session identifier, this makes the amount of personal information that a website can save about each user virtually limitless—the website is not limited to restrictions concerning how large a cookie can be.

Session cookies also help to improve page load times, since the amount of information in a session cookie is small and requires little bandwidth.

For example, a web server might send a cookie containing the username that was last used to log into a website, so that it may be filled in automatically the next time the user logs in.

Many websites use cookies for personalization based on the user's preferences. Users select their preferences by entering them in a web form and submitting the form to the server.

The server encodes the preferences in a cookie and sends the cookie back to the browser. This way, every time the user accesses a page on the website, the server can personalize the page according to the user's preferences.

For example, the Google search engine once used cookies to allow users even non-registered ones to decide how many search results per page they wanted to see.

Also, DuckDuckGo uses cookies to allow users to set the viewing preferences like colors of the web page.
