Simple rack middleware utility to make sure the upcoming standard DNT header is always available. This will normalize things like the X-Do-Not-Track header that may be floating around, allow for server override, and default to 0 (allow tracking, the proposed browser default) if there's no better option.
gem install donottrack
# Default behavior
use Rack::DoNotTrack
# Manual override (always enable do not track)
use Rack::DoNotTrack, 1
Both of these will ensure that, in Rails for instance, request.headers['HTTP_DNT'] will always be available.
