As a Netscape Communications employee, Montulli worked alongside John Giannandrea to develop cookies into a unique solution that would help make shopping carts for e-commerce stores possible.
At the start, all supported browsers accepted cookies by default, which meant hardly any end users were aware of their use or presence.
However, in February , this changed, when their use, purpose, and existence were revealed in a piece published by The Financial Times.
Over the next few years, the media placed cookies under intense scrutiny due to the privacy risks created as they tracked visitors across a website.
However, there are other legalities that have come into play with regards to cookies. For each specific user, there will be bits of data that are associated with them by cookies.
At a minimum, cookies contain two bits of data: an identifier for a unique user and some information about this user.
This should hopefully add to your understanding of how they are used as well as how they work. The first, "theme", is considered to be a session cookie since it does not have an Expires or Max-Age attribute.
Session cookies are intended to be deleted by the browser when the browser closes. The second, "sessionToken", is considered to be a persistent cookie since it contains an Expires attribute, which instructs the browser to delete the cookie at a specific date and time.
Next, the browser sends another request to visit the spec. This request contains a Cookie HTTP header, which contains the two cookies that the server instructed the browser to set:.
This way, the server knows that this request is related to the previous one. The server would answer by sending the requested page, possibly including more Set-Cookie headers in the response in order to add new cookies, modify existing cookies, or delete cookies.
The value of a cookie can be modified by the server by including a Set-Cookie header in response to a page request.
The browser then replaces the old value with the new value. The cookie standard RFC is more restrictive but not implemented by browsers. The term "cookie crumb" is sometimes used to refer to a cookie's name—value pair.
In addition to a name and value, cookies can also have one or more attributes. Browsers do not include cookie attributes in requests to the server—they only send the cookie's name and value.
Cookie attributes are used by browsers to determine when to delete a cookie, block a cookie or whether to send a cookie to the server. The Domain and Path attributes define the scope of the cookie.
They essentially tell the browser what website the cookie belongs to. For obvious security reasons, cookies can only be set on the current resource's top domain and its sub domains, and not for another domain and its sub domains.
For example, the website example. If a cookie's Domain and Path attributes are not specified by the server, they default to the domain and path of the resource that was requested.
In the former case, the cookie will only be sent for requests to foo. In the latter case, all sub domains are also included for example, docs.
The HTTP request was sent to a webpage within the docs. This tells the browser to use the cookie only when requesting pages contained in docs.
The prepending dot is optional in recent standards, but can be added for compatibility with RFC based implementations.
The Expires attribute defines a specific date and time for when the browser should delete the cookie. Alternatively, the Max-Age attribute can be used to set the cookie's expiration as an interval of seconds in the future, relative to the time the browser received the cookie.
Below is an example of three Set-Cookie headers that were received from a website after a user logged in:. The first cookie, lu , is set to expire sometime on 15 January It will be used by the client browser until that time.
It will be deleted after the user closes their browser. The browser will delete this cookie right away because its expiration time is in the past.
Note that cookie will only be deleted if the domain and path attributes in the Set-Cookie field match the values used when the cookie was created.
As of [update] Internet Explorer did not support Max-Age. The Secure and HttpOnly attributes do not have associated values.
Rather, the presence of just their attribute names indicates that their behaviors should be enabled. However, if a web server sets a cookie with a secure attribute from a non-secure connection, the cookie can still be intercepted when it is sent to the user by man-in-the-middle attacks.
Most modern browsers support cookies and allow the user to disable them. The following are common options: .
Add-on tools for managing cookie permissions also exist. Cookies have some important implications on the privacy and anonymity of web users. While cookies are sent only to the server setting them or a server in the same Internet domain, a web page may contain images or other components stored on servers in other domains.
Cookies that are set during retrieval of these components are called third-party cookies. The older standards for cookies, RFC and RFC , specify that browsers should protect user privacy and not allow sharing of cookies between servers by default.
Newer versions of Safari block third-party cookies, and this is planned for Mozilla Firefox as well initially planned for version 22 but postponed indefinitely.
Advertising companies use third-party cookies to track a user across multiple sites. In particular, an advertising company can track a user across all pages where it has placed advertising images or web bugs.
Knowledge of the pages visited by a user allows the advertising company to target advertisements to the user's presumed preferences.
Website operators who do not disclose third-party cookie use to consumers run the risk of harming consumer trust if cookie use is discovered.
The possibility of building a profile of users is a privacy threat, especially when tracking is done across multiple domains using third-party cookies.
For this reason, some countries have legislation about cookies. The United States government has set strict rules on setting cookies in after it was disclosed that the White House drug policy office used cookies to track computer users viewing its online anti-drug advertising.
In , privacy activist Daniel Brandt found that the CIA had been leaving persistent cookies on computers that had visited its website.
When notified it was violating policy, CIA stated that these cookies were not intentionally set and stopped setting them. After being informed, the NSA immediately disabled the cookies.
In , the European Union launched the Directive on Privacy and Electronic Communications , a policy requiring end users' consent for the placement of cookies, and similar technologies for storing and accessing information on users' equipment.
Instead of having an option for users to opt out of cookie storage, the revised Directive requires consent to be obtained for cookie storage.
In June , European data protection authorities adopted an opinion which clarifies that some cookie users might be exempt from the requirement to gain consent:.
The industry's response has been largely negative. The document. But it is not. Even if you write a whole cookie string to document. If you set a new cookie, older cookies are not overwritten.
It illustrates how to delete a cookie by setting its expiry date to one month behind the current date.

The top answer clearly isn't the best.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.
