thank you very much, I think this is the right answer for me.
But please just a little more help: where can I define this property to work 
both in the Back End and Front End?

I tried to define it il localconf.php adding this line:
$TYPO3_CONF_VARS["config"]["additionalHeaders"] = 'P3P: 
CP="myPrivacyPolicy"';
and I can see it under config > additionalHeaders, but it seems to have no 
effects.
