What are cookies & how do I use them?
Jan 30, 2014 · You are correct, yes, you can read the cookies' contents, because it's your computer. But that doesn't mean that the browser will let any website read them. So, those are two different things. You may also have some personal files on your computer which YOU can read but a website can't. You have an interesting question.
Analytics cookies are used so online services can collect information about how people access them – for example, the number of users on a website, how long they stay on the site for, and what parts of the site they visit.
What are ‘cookies’? Cookies are small pieces of information, normally consisting of just letters and numbers, which online services provide when users visit them. Software on the user's device (for example a web browser) can store cookies and send them back to the website next time they visit.
This guidance addresses cookies and similar technologies in detail. Read it if you operate an online service, such as a website or a mobile app, and need a deeper understanding of how PECR applies to your use of cookies.

An HTTP cookie (web cookie, browser cookie) is a small piece of data that a server sends to a user's web browser. The browser may store the cookie and send it back to the same server with later requests. Typically, an HTTP cookie is used to tell if two requests come from the same browser—keeping a user logged in, for example. It remembers stateful information for the stateless HTTP protocol.
Cookies are mainly used for three purposes:
Session management
Logins, shopping carts, game scores, or anything else the server should remember
Personalization
User preferences, themes, and other settings
After receiving an HTTP request, a server can send one or more Set-Cookie headers with the response. The browser usually stores the cookie and sends it with requests made to the same server inside a Cookie HTTP header. You can specify an expiration date or time period after which the cookie shouldn't be sent. You can also set additional restriction...
Ways to mitigate attacks involving cookies:
•Use the HttpOnly attribute to prevent access to cookie values via JavaScript.
Third-party cookies
A cookie is associated with a particular domain and scheme (such as http or https), and may also be associated with subdomains if the Set-Cookie Domain attribute is set. If the cookie domain and scheme match the current page, the cookie is considered to be from the same site as the page, and is referred to as a first-party cookie. If the domain and scheme are different, the cookie is not considered to be from the same site, and is referred to as a third-party cookie. While the server hosting a web page sets first-party cookies, the page may contain components stored on servers in other domains, such as images or other documents embedded in s. These components may set third-party cookies. Typical use cases for third-party cookies include sharing user profile information or collecting analytics across different related domains. They are also often used for advertising and tracking users across the web. A third-party server can create 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) not to function as intended. There are some useful features available for developers who wish to respect user privacy, and minimize third-party tracking: •Servers can (and should) set the cookie SameSite attribute to specify whether or not third-party cookies may be sent. •Cookies Having Independent Partitioned State (CHIPS) enables developers to opt-in their cookies to partitioned storage, with a separate cookie jar per top-level site. This enables valid non-tracking uses of third-party cookies to continue working in browsers that do not allow cookies to be used for third-party tracking.
Cookie-related regulations
Legislation or regulations that cover the use of cookies include: •The General Data Privacy Regulation (GDPR) in the European Union •The ePrivacy Directive in the EU •The California Consumer Privacy Act These regulations have global reach. They apply to any site on the World Wide Web that users from these jurisdictions access (the EU and California, with the caveat that California's law applies only to entities with gross revenue over 25 million USD, among things). These regulations include requirements such as: •Notifying users that your site uses cookies. •Allowing users to opt out of receiving some or all cookies. •Allowing users to use the bulk of your service without receiving cookies.
Another approach to storing data in the browser is the Web Storage API. The window.sessionStorage and window.localStorage properties correspond to session and permanent cookies in duration, but have larger storage limits than cookies, and are never sent to a server. More structured and larger amounts of data can be stored using the IndexedDB API, or a library built on it.
There are some techniques designed to recreate cookies after they're deleted. These are known as "zombie" cookies. These techniques violate the principles of user privacy and user control, may violate data privacy regulations, and could expose a website using them to legal liability.
Learn more. 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.
