This information is sometimes stored on your computer in a simple text file which the server accesses in order to read and store the information.
A cookie has several different functions. It can enable the server that has placed it to recognise the user from one visit to the next by means of a unique identifier.
Certain cookies can also be used to store the content of a shopping basket, others store the language parameters of a website and some enable targeted advertising.
An Internet website can only read and write cookies which belong to it.
It should be remembered however that a page on the Internet can often contain information from different websites, particularly via advertising banners. Cookies therefore can be placed and read by sites other than the one you are directly visiting.
For example, if you surf on a news website, it is possible that other sites – advertising for example – can obtain information on your surfing. To do this, the advertisers place a cookie on the new website that you are looking at.
Advertising cookies record information on how users surf and can work out their interests and surfing habits on that website. This then enables companies to personalise the advertising which the user will see based on what he or she has done on the website they have visited, and also based on other sites containing the same advertising.
The http://tickets.rolandgarros.com website uses audience measuring and analysis tools.
