Abstract This document defines the HTTP Cookie and Set-Cookie header fields. expose cookies via non-HTTP APIs, such as HTML's donboscoforum.com API. 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.

If the cookie is not found, return "". 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. What are Website Cookies? Cookies are small and specific packets of data that a visitor’s computer receives and sends. These packets of data are stored on the visitor’s web browser and can be accessed by a web server also. Cookies help to monitor and keep track of user’s activities on a website.

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.

Previously the default was that cookies were sent for all requests. Last modified: Nov 29, , by MDN contributors.

JavaScript can read, create, modify, and delete the cookies that apply to the current web page. The simplest way to create a cookie is to assign a string value to the document.

Here the expires attribute is optional. If you provide this attribute with a valid date or time, then the cookie will expire on a given date or time and thereafter, the cookies' value will not be accessible.

For this reason, you may want to use the JavaScript escape function to encode the value before storing it in the cookie.

If you do this, you will also have to use the corresponding unescape function when you read the cookie value. Now your machine has a cookie called name.

Reading a cookie is just as simple as writing one, because the value of the document. So you can use this string whenever you want to access the cookie.

Furthermore, some systems, such as Tor , are designed to retain Internet anonymity , rendering tracking by IP address impractical, impossible, or a security risk.

A more precise technique is based on embedding information into URLs. The query string part of the URL is the part that is typically used for this purpose, but other parts can be used as well.

This method consists of the web server appending query strings containing a unique session identifier to all the links inside of a web page.

When the user follows a link, the browser sends the query string to the server, allowing the server to identify the user and maintain state.

These kinds of query strings are very similar to cookies in that both contain arbitrary pieces of information chosen by the server and both are sent back to the server on every request.

However, there are some differences. Since a query string is part of a URL, if that URL is later reused, the same attached piece of information will be sent to the server, which could lead to confusion.

For example, if the preferences of a user are encoded in the query string of a URL and the user sends this URL to another user by e-mail , those preferences will be used for that other user as well.

Moreover, if the same user accesses the same page multiple times from different sources, there is no guarantee that the same query string will be used each time.

For example, if a user visits a page by coming from a page internal to the site the first time, and then visits the same page by coming from an external search engine the second time, the query strings would likely be different.

If cookies were used in this situation, the cookies would be the same. Other drawbacks of query strings are related to security. Storing data that identifies a session in a query string enables session fixation attacks, referer logging attacks and other security exploits.

Transferring session identifiers as HTTP cookies is more secure. Another form of session tracking is to use web forms with hidden fields.

This technique is very similar to using URL query strings to hold the information and has many of the same advantages and drawbacks.

This approach presents two advantages from the point of view of the tracker. First, having the tracking information placed in the HTTP request body rather than in the URL means it will not be noticed by the average user.

Second, the session information is not copied when the user copies the URL to bookmark the page or send it via email, for example.

This data can be used instead of session cookies and is also cross-domain. The downside is that every separate window or tab will initially have an empty window.

Furthermore, the property can be used for tracking visitors across different websites, making it of concern for Internet privacy.

In some respects, this can be more secure than cookies due to the fact that its contents are not automatically sent to the server on every request like cookies are, so it is not vulnerable to network cookie sniffing attacks.

However, if special measures are not taken to protect the data, it is vulnerable to other attacks because the data is available across different websites opened in the same window or tab.

Apple uses a tracking technique called "identifier for advertisers" IDFA. This technique assigns a unique identifier to every user who buys an Apple iOS device such as an iPhone or iPad.

This identifier is then used by Apple's advertising network, iAd, to determine the ads that individuals are viewing and responding to.

Because ETags are cached by the browser, and returned with subsequent requests for the same resource, a tracking server can simply repeat any ETag received from the browser to ensure an assigned ETag persists indefinitely in a similar way to persistent cookies.

Additional caching headers can also enhance the preservation of ETag data. ETags can be flushed in some browsers by clearing the browser cache.

Some web browsers support persistence mechanisms which allow the page to store the information locally for later use. The HTML5 standard which most modern web browsers support to some extent includes a JavaScript API called Web storage that allows two types of storage: local storage and session storage.

Internet Explorer supports persistent information [80] in the browser's history, in the browser's favorites, in an XML store "user data" , or directly within a web page saved to disk.

Some web browser plugins include persistence mechanisms as well. The browser cache can also be used to store information that can be used to track individual users.

This technique takes advantage of the fact that the web browser will use resources stored within the cache instead of downloading them from the website when it determines that the cache already has the most up-to-date version of the resource.

After the user's initial visit, every time the user accesses the page, this file will be loaded from the cache instead of downloaded from the server.

Thus, its content will never change. A browser fingerprint is information collected about a browser's configuration, such as version number, screen resolution, and operating system, for the purpose of identification.

Fingerprints can be used to fully or partially identify individual users or devices even when cookies are turned off.

Basic web browser configuration information has long been collected by web analytics services in an effort to accurately measure real human web traffic and discount various forms of click fraud.

With the assistance of client-side scripting languages, collection of much more esoteric parameters is possible.
