At first glance, it would seem to a person familiar with using the resources of the global Internet network that, in addition to annoying advertising on websites, there are no special features: the selected program for viewing pages (browser) sends requests, and distant servers return a response.
In fact, everything is a little more complicated and there are some features that significantly expand the request-response scheme. One of them is cookies. They are small files of 4 kilobytes in size, containing certain textual information. Often users do not even suspect that their browser is actively using cookies. When a user Internet client accesses the server, the latter sends a special file to the computer - cookies. It contains information that identifies the user. In the future, each new connection to this resource begins with the browser sending such a file to the server. As a result, the user enters the site already with his username / password, and the page is displayed exactly as it was configured during the previous visit. Here is an example with a TV program website: a visitor registers and selects a list of displayed channels. If the server involves the use of cookies, then when you visit this site the next time only selected channels will be displayed. In fact, the possibilities are much wider, but their review is beyond the scope of the article.
Since these small files contain information that allows you to identify the visitor, it is quite clear why the question “How to clear cookies?” Is often asked. If the computer is in sole use, then you can not really think about such security. But with the possibility of access to the system of third parties, they have the opportunity to access sites using data stored in cookies. A user who does not know how to clear cookies or who has not completed this operation in a timely manner is at risk of making purchases from his accounts and some other troubles, such as viewing all the pages visited by him. Obviously, you should not forget about safety.
Before learning how to clear cookies, it should be noted that these small files are still needed, since they greatly simplify the work on the Web. Therefore, it is recommended to save the cookie on a separate medium or archive it with a password. Sometimes such an archive is simply indispensable.
The answer to the question "How to delete cookies?" Depends on the browser used. In each of them, you can select several operating modes: delete cookies when exiting the browser, do not accept at all, display a request.
If the user uses Opera, but does not know how to clear cookies, then proceed as follows: press Ctrl + F12 in the browser, go to “Advanced” and select “Cookies”. By pressing the control button, you can erase objectionable entries.
Firefox is even easier: Settings - Privacy. In the “Delete individual cookies” menu, it is possible to delete them selectively or all at once.
In the Internet Explorer included with Windows, select “General” in the properties, where in the browsing history delete temporary Internet files .
In Google Chrome, you need to open the settings, select the advanced view and, having put the necessary checkmarks, selectively clear the history.
There is a more convenient way to clear cookies. It consists in the use of special programs. One of the most popular is CCleaner. In it you need to click "Clear" and select cookies. The program has great capabilities, so we remove the checkmarks from those operations that are not required to be performed. In the settings you can specify which cookies you want to save. It is not recommended to ignore the creation of a backup reg-file: its size is small, but with possible problems it is easy to restore the previous state of the registry.
