Cookies are small files that are stored on a user’s computer. They are designed to contain a modest amount of site- and website-specific data and can be accessed by either the web server or the client computer. This allows the server to deliver a page tailored to a particular user, or the page itself may contain a script that contains cookies, and thus may carry information from one visit to the next website (or website). .


To check if your browser is set to allow cookies, go to Cookie Checker. This page will try to create a cookie and report whether or not it was successful.

For information on how to enable or disable cookies, see “Enabling cookies”.

Can I view / view the cookies I have on my computer?

Most browsers have a configuration screen that allows the user to see which cookies have been stored on your computer and to delete them optionally. For more information, see the cookie preview page.

Please note that a webpage may not display cookies set by other sites, as they would privacy and security.


Each cookie is actually a small search table that contains pairs of values ​​(key, data) – e.g. John) (first name, Smith). Once the cookie has been read by the code on the server or client computer, the data can be retrieved and used to properly personalize the web page.

When are cookies created?

Data is usually written on a cookie when a new web page is loaded – for example, after pressing a “Submit” button, the data management page will be responsible for storing the values ​​in a cookie. If the user has chosen to disable cookies, then the write operation will fail, and subsequent cookie-based sites will be required to take a default action or prompt the user to re-enter the information stored in the cookie.


Cookies are a convenient way to carry information from one session on one website to another or between sessions on related websites, without being you need to load a server machine with massive amounts of data storage. Storing data on the server without the use of cookies would also be problematic, as it would be difficult to obtain information from a particular user without requiring authentication each time you visit the website.

If any a large amount of information stored, then a cookie can simply be used as a means of identifying a particular user, so that additional related information can be searched in a database on the server. For example, the first time a user visits a site, they can choose a username that is stored in the cookie and then provide data such as password, name, address, preferred font size, page layout, and so on. – all this information would be stored in the database using the username as the key. Later, when the site is reviewed, the server will read the cookie to find the username and then retrieve all the user information from the database without re-entering it.


The cookie expiration time can be set when the cookie is created. By default, the cookie is destroyed when the current browser window is closed, but an arbitrary period may persist after that.

Who can access cookies?

When created a cookie, you can control its visibility by setting the “root domain”. It will then be accessible to any URL that belongs to that root. For example, the root could be set to “”, and the cookie would then be available for “” or “” or “”.It can be used to allow related pages to “communicate” with each other. It is not possible to set the root domain to “top-level” domains, such as “.com” or “”, as this would allow wide access to the cookie.

By default , cookies are visible to all paths in their domain, but at the time of creation, they may be restricted to a specific subpath – for example “”.

There are many concerns with on privacy and security on the Internet. Cookies do not in themselves constitute a threat to privacy, as they can only be used to store information that the user has voluntarily provided or already has with the web server. Although this information may be made available to certain third party websites, it is no worse than storing it in a central database. If you are concerned that the information you provide to a web server will not be considered confidential, then you should ask yourself if you actually need to provide this information.

What are tracking cookies?

Some commercial sites include embedded advertising material that is provided from a third party site, and such advertisements may store a cookie for that third party site, which contains information that is provided to them by the site. – such information may include site names, certain products viewed, pages visited, etc. When the user later visits another site that contains a similar embedded ad on the same third-party site, the advertiser will be able to read the cookie and use it to determine some information about the user’s browsing history.
