Forgive me if this is a silly question, but is there a mechanism for the client to check whether the site has been updated to avoid having to pull down that big ol’ blob o’ JSON if it’s not necessary? My first guess would have been to check for a Last-Modified header and compare with the header on the previous fetch, but it doesn’t look like the server sets that header. I guess you could use Content-Length, but that’s a bit crude. There’s .site_view.site.updated, which would fit the bill if accurate, but you’d still have to do a partial download and then pull it out with regex or something since the JSON structure would be mangled, which makes me think there ought to be a better way.
