The parameters of the function above are the name of the cookie cname , the value of the cookie cvalue , and the number of days until the cookie should expire exdays.
The function sets a cookie by adding together the cookiename, the cookie value, and the expires string. Then, we create a function that returns the value of a specified cookie:.
If the cookie is found c. If the cookie is not set, it will display a prompt box, asking for the name of the user, and stores the username cookie for days, by calling the setCookie function:.
The example above runs the checkCookie function when the page loads. Firefox Full support Yes. IE Full support Yes. Opera Full support Yes.
Safari Full support Yes. 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.

W3schools states it is stored on the computer. Petty, but so is the bashing of W3schools. Just use the setCookie and getCookie methods mentioned there.

BT, I've yet to see a reference on w3schools that is out of date or contains incorrect information. So using 'max-age' is a pretty bad idea.
Two of the primary uses of cookies are for affiliate sales and advertising through third-party tracking. Complying with these three guidelines will help you to stick to the various laws that are in place.
These websites and tutorials will help you decipher what information you need to create the cookies on your application or website:. Even though they provide a website with features that are business critical, they also present users with a number of privacy and security issues.
Therefore, educating yourself on how cookies work and how you can protect yourself from cookie fraud and invasion of your privacy, you can be better prepared to take advantage of them without putting yourself at any risk.

Note that each key and value may be surrounded by whitespace space and tab characters : in fact, RFC mandates a single space after each semicolon, but some user agents may not abide by this.
Consider also that:. When user privacy is a concern, it's important that any web app implementation invalidate cookie data after a certain timeout instead of relying on the browser to do it.
Many browsers let users specify that cookies should never expire, which is not necessarily safe. In order to use the following code, please replace all occurrences of the word doSomethingOnlyOnce the name of the cookie with a custom name.
It is important to note that the path attribute does not protect against unauthorized reading of the cookie from a different path.
It can be easily bypassed using the DOM, for example by creating a hidden represents a nested browsing context, embedding another HTML page into the current one.
