You can extend the life of a cookie beyond the current browser session by setting an expiration date and saving the expiry date within the cookie.
Sometimes you will want to delete a cookie so that subsequent attempts to read the cookie return nothing. To do this, you just need to set the expiry date to a time in the past.
Try the following example. 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.
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.

Previously the default was that cookies were sent for all requests. Last modified: Nov 29, , by MDN contributors. Some users may be tracked based on the IP address of the computer requesting the page.
The server knows the IP address of the computer running the browser or the proxy , if any is used and could theoretically link a user's session to this IP address.
However, IP addresses are generally not a reliable way to track a session or identify a user. This means that several PCs will share a public IP address.
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.
Internet Explorer supports persistent information  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.
