Okay. So, distinct header, registering refresh=1 or [nothing] in the
x-analytics field when it hits the varnish layer? Rocking! Let me know
what happens/where it goes/when it goes/etc.

The RESTbase services, yeah; they're going to make an impact. Not just
in format either (I have literally no idea how the caching setup there
works, if there is a caching setup, or which varnish cluster any such
caching setup would go through and so if we're even picking up those
requests at all).
