[dmurph]

What are the http headers here? Should we include information about the app? What referrer policy should be used?

Is this in service of https://docs.google.com/document/d/1RuxUf8LGbaVfLvIOTorXUa__7cN56r54tQFwd3l45Es/edit#heading=h.tph42uvwe9i ?

@alancutter - no not in service of that doc, just being explicit about what the fetch model should be I think?

@marcoscaceres Do you mind helping us out for how we might define the headers here / the referrer policy / fetch model? What might we say / reference here?
