Of course if you agree that "non-compliant = invalid".  :)

Shane,

Does "invalid UA" mean the same thing as "non-compliant UA"?   Or do you mean "invalid" to be broader somehow?

Peter,

That is up to the Server to make the choice to reply with an "Invalid UA" response and provide users with options from that point forward.  That Server will need to defend its position to consumers, advocates, etc. but should absolutely have that option.  Whatever overhead that comes that choice (PR defense, coding overhead, etc.) is the Servers to manage from that point forward.

Shane,



The server does need to know because it's about to reject it. MSIE is non compliant in only ONE aspect - it sets the flag by default. In EVERY other aspect it is COMPLIANT because the user can change that preference.



So in essence you're saying that if you see a UA of MSIE 10 you're going to reject it immediately and send back a 400 message. Get ready to start writing lots of scripts or modules (your preference)



Peter

Peter,



The Server doesn't need to know - I believe that's the point you're missing.  The user installed a non-compliant UA and the Server will respond as such.  The user then has multiple options to exercise their choice but continued use of that specific UA to communicate DNT is NOT one of them.
