@konklone They can move the tracking to a lower level like TCP or IP, e.g. encoding the tracking id in your IPv6 address or TCP options.
@BRIAN_____ While I'm not a TCP/IP expert, that seems harder to pull off at scale and far less valuable.
@konklone It seems easy:
ISP assigns IP address: address = user_id.
Partner's front-end server retrieves user ID: user_id = address.
@BRIAN_____ but no more URL paths, post bodies, or cookies, and partners have to receive information at the IP level and not the HTTP level.
