Okay, here is my attempt to address the comments that were made during and prior to today's teleconference. ....Roy http://www.w3.org/2011/tracking-protection/drafts/tracking-dnt.html#TSV-G 6.2.4 Gateway (G) A tracking status value of G means the server is acting as a gateway to an exchange involving multiple parties. This might occur if a response to the designated resource involves an automated selection process, such as dynamic bidding, where the party that is selected determines how the request data will be treated with respect to an expressed tracking preference. Similar to the ? value, the G TSV indicates that the actual tracking status is dynamic and will be provided in the response message's Tk header field, presumably using information forwarded from the selected party. This tracking status value is only valid as a site-wide status. A server MUST NOT send G as the tracking status value in a Tk header field or within the representation of a request-specific tracking status resource. If G is present in the site-wide tracking status: * the gateway MUST send a link within its site-wide tracking status representation to a privacy policy that explains what limitations are placed on parties that might receive data via that gateway; * the gateway MUST forward any expressed tracking preference in the request to each party that receives data from that request; * the gateway MUST have a contract in place with each of the parties to whom it provides request data such that only the selected party is allowed to retain tracking data from a request with an expressed tracking preference of DNT:1; and, * the gateway MUST send a Tk header field in responses to requests on the designated resource and include within that field's value a status-id specific to the selected party, such that information about the selected party can be obtained via the request-specific tracking status resource (see section 6.4.2 Request-specific Tracking Status). With respect to tracking performed by the gateway itself, the G response can be considered equivalent to the T (tracking) response defined below. The other information within the site-wide tracking status representation indicates how the gateway intends to comply with an expressed tracking preference, aside from the potential sharing of data implied by the gateway process.
