How would the server know? It all sees is either a 1, 0 or null value.

And therein lies the problem with DNT. It has to be location aware “IF” the user sends a No Preference value (Null). What if something injects a Null value after the user has made a DNT=1 setting. Because the protocol has no requirement to even echo back that it received a value let alone what the original value was the user is none the wiser. He/she just expects to Not Be Tracked or maybe tracked depending on where he is. Peter
