Subject: Send the first JSON inline.
X-Git-Url: https://git.sesse.net/?p=remoteglot;a=commitdiff_plain;h=b4498c56489f3accf18014c17b771fa61e7888b9

Send the first JSON inline.

This removes a round-trip, although it's probably slightly less bandwidth-efficient
and definitely more complex. You'll need to make Varnish rewrite / to /index-inline.html
and send it to the backend. It doesn't work on the .dev version, unfortunately.
