Tracking users is common on the web.


A web site can search for resources such as images and scripts on domains other than its own. This is called "cross-origin" or "cross-site loading" - and it's what makes the web so powerful. However, this feature also makes it possible to track users from one site to another. The famous cookies stored in the user's browser enable "cross-site tracking" and provide information about user behavior across the web to the owner of the cookie.


A very large number of sites use cookies; they must announce them and allow the user to accept and choose the type of cookie he/she wants to authorize.


Smile, you're under watch !
