RE: Multiple DNT Headers (ACTION-283, ISSUE-150)

Alternate Text for Conflicting Headers:

If a server receives conflicting DNT headers, it MAY choose to treat the transaction as if no DNT header had been received.  The Server MAY choose to alert the user about possible user agent configuration issues causing multiple, conflicting DNT header signals to be received.

Proposed text on duplicate headers:

If a server receives duplicate DNT headers, it MUST act as if it had received a single DNT header.

Proposed text on conflicting headers:

If a server receives conflicting DNT headers, it MUST act as if it had received a single DNT: 1 header. It is a best practice for the server to alert the user about possible user agent misconfiguration.
