Should we try to just reply differently to that User-Agent and DTRT
for
it? And then set "Vary: User-Agent" in the response?
We could, but where? In Varnish or in the flask app by not sending the
redirect but serving the file directly?
Good question. I had Varnish in mind because it can easily retry the
request - and already does. I don't know of a way of doing this in
Apache. I think it'd be mostly trivial with nginx, but right now we are
stuck with Apache.
I.e. we could do literally what you suggested but key it off the
User-Agent and set the Vary header?

I think that could be done using mod_rewrite rules. I /think/ (but am
not sure) that mod_rewrite unescapes before processing args. And you
can
forward bits using E=. So we... could. It's just messy.
I just did this, and surprisingly it works! The Apache rules are in the
MR as well.

Nice, that's awesome!
