*  linkObfuscator manages a simple way of validating links: starting from a session, an user can browse exclusively those links that are performed by this page. to do this, a random seed is generated and a special code (named go) is attached to each link.
* each page that has to be obfuscated needs this class and a $linkObfuscator::check() to validate the user.
