HTTP cookies (also called web cookies, Internet cookies, browser

cookies, or simply cookies) are small blocks of data created by a web


server while a user is browsing a website and placed on the user's computer or
other device by the user's web browser. Cookies are placed on the device used
to access a website, and more than one cookie may be placed on a user's
device during a session.
Cookies serve useful and sometimes essential functions on the web. They
enable web servers to store stateful information (such as items added in the
shopping cart in an online store) on the user's device or to track the user's
browsing activity (including clicking particular buttons, logging in, or recording
which pages were visited in the past).[1] They can also be used to save
information that the user previously entered into form fields, such as names,
addresses, passwords, and payment card numbers for subsequent use.
Authentication cookies are commonly used by web servers
to authenticate that a user is logged in, and with which account they are
logged in. Without the cookie, users would need to authenticate themselves by
logging in on each page containing sensitive information that they wish to
access. The security of an authentication cookie generally depends on the
security of the issuing website and the user's web browser, and on whether the
cookie data is encrypted. Security vulnerabilities may allow a cookie's data to
be read by an attacker, used to gain access to user data, or used to gain
access (with the user's credentials) to the website to which the cookie belongs
(see cross-site scripting and cross-site request forgery for examples).[2]
Tracking cookies, and especially third-party tracking cookies, are commonly
used as ways to compile long-term records of individuals' browsing histories —
a potential privacy concern that prompted European[3] and U.S. lawmakers to
take action in 2011.[4][5] European law requires that all websites
targeting European Union member states gain "informed consent" from users
before storing non-essential cookies on their device.
