A cookie is often used to identify a user. A cookie is a small file that the server embeds on the user's computer. Each time the same computer requests a page with a browser, it will send the cookie too.
With PHP, you can both create and retrieve cookie values. The following example creates a cookie named "user" with the value "John Doe".
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.
Therefore, for maximum security, cookies with the Secure attribute should only be set over a secure connection.
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. Robert Bond of the law firm Speechly Bircham describes the effects as "far-reaching and incredibly onerous" for "all UK companies".
Simon Davis of Privacy International argues that proper enforcement would "destroy the entire industry". Thus, cookies can be qualified as personal data and are therefore subject to GDPR.
However, the P3P specification was criticized by web developers for its complexity. Some websites do not correctly implement it. Third-party cookies can be blocked by most browsers to increase privacy and reduce tracking by advertising and tracking companies without negatively affecting the user's web experience.
Many advertising operators have an opt-out option to behavioural advertising, with a generic cookie in the browser stopping behavioural advertising.
From the web server's point of view, a request from an attacker then has the same authentication as the victim's requests; thus the request is performed on behalf of the victim's session.
Listed here are various scenarios of cookie theft and user session hijacking even without stealing user cookies that work with websites relying solely on HTTP cookies for user identification.
Traffic on a network can be intercepted and read by computers on the network other than the sender and receiver particularly over unencrypted open Wi-Fi.
This traffic includes cookies sent on ordinary unencrypted HTTP sessions. Where network traffic is not encrypted, attackers can therefore read the communications of other users on the network, including HTTP cookies as well as the entire contents of the conversations, for the purpose of a man-in-the-middle attack.
An attacker could use intercepted cookies to impersonate a user and perform a malicious task, such as transferring money out of the victim's bank account.
This issue can be resolved by securing the communication between the user's computer and the server by employing Transport Layer Security HTTPS protocol to encrypt the connection.
A server can specify the Secure flag while setting a cookie, which will cause the browser to send the cookie only over an encrypted channel, such as an TLS connection.
If an attacker is able to cause a DNS server to cache a fabricated DNS entry called DNS cache poisoning , then this could allow the attacker to gain access to a user's cookies.
Victims reading the attacker's message would download this image from f Since f If an attacker is able to accomplish this, it is usually the fault of the Internet Service Providers for not properly securing their DNS servers.
However, the severity of this attack can be lessened if the target website uses secure cookies.
In this case, the attacker would have the extra challenge  of obtaining the target website's TLS certificate from a certificate authority , since secure cookies can only be transmitted over an encrypted connection.
Without a matching TLS certificate, victims' browsers would display a warning message about the attacker's invalid certificate, which would help deter users from visiting the attacker's fraudulent website and sending the attacker their cookies.
As an example, an attacker may post a message on www. Safari Full support Yes. WebView Android Full support Yes. Chrome Android Full support Yes.

If you do this, you will also have to use the corresponding unescape function when you read the cookie value.
Now your machine has a cookie called name. Reading a cookie is just as simple as writing one, because the value of the document.
So you can use this string whenever you want to access the cookie. The document. We will discuss Arrays in a separate chapter. By that time, please try to digest it.
