If you actually look at w3fools you'll see that they have actually removed all the content from their website presumably because all their criticisms are invalid.
It just annoys me when I see people get on the 'w3fools' bandwagon without using their own judgement.
CpnCrunch W3schools destroyed their brand a decade ago. I won't apologize for not trusting them. The only thing they've been good at for 10 years is SEO.
BT quirks says "A cookie is nothing but a small text file that's stored in your browser. Must be new. W3schools states it is stored on the computer.
First, we create a function that stores the name of the visitor in a cookie variable:. 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. For this reason, persistent cookies are sometimes referred to as tracking cookies because they can be used by advertisers to record information about a user's web browsing habits over an extended period of time.
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  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 ,  Firefox ,  and Brave ,  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  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.
When the cookie's absence is detected, [ clarification needed ] the cookie is recreated [ clarification needed ] using the data stored in these locations.
A cookie consists of the following components:  . Cookies were originally introduced to provide a way for users to record items they want to purchase as they navigate throughout a website a virtual "shopping cart" or "shopping basket".
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.
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.
Cookies can be used to remember information about the user in order to show relevant content to that user over time. 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.
Even though cookie fraud is a concern for many people, the greater worry is the risk posed by the invasion of privacy. In fact, a lot of users feel as though the use of the information by Google to provide targeted ads is a tad creepy, to say the least.
Many other web advertising platforms, such as Facebook, Disqus, Revcontent, and Infolinks, are trying to improve user targeting and the delivery of relevant ads by mining more and more data about each and every user.
But, there are a number of things you can do which limit how much time your privacy is invaded by cookies:. The process of viewing and deleting the cookies stored by your browser is relatively easy, especially with most modern browsers.
Here, you should be able to locate an option which allows you to see the cookies that have been stored. So, this cookie will be like a bad smell and will continue to reappear.
