334 * The "typename" seperates the security tokens of different types of forms. This could be relevant in the following case:
335 * A security token is used to protekt a link from CSRF (e.g. the "delete this profile"-link).
336 * If the new page contains by any chance external elements, then the used security token is exposed by the referrer.
337 * Actually, important actions should not be triggered by Links / GET-Requests at all, but somethimes they still are,
338 * so this mechanism brings in some damage control (the attacker would be able to forge a request to a form of this type, but not to forms of other types).
