No, I'm not using mod_rewrite, but I think that's really irrelevant.
mod_rewrite can't "force" HTTPS. HTTPS is an end to end encryption,
which means it can't just be switched into HTTPS mode. You have to
start the request all over, with the client initiating the HTTPS
session. So all mod_rewrite can really do is tell the browser "hey,
start again, but use HTTPS this time". From then on, it should behave
exactly the same as if HTTPS was explicitly requested.

I really suspect there's something else at play here, and that the
mod_rewrite has nothing to do with your problem. What happens if you
disable all of your mod_rewrite settings and then just make sure you
type https:// in your browser? Does that work right? If not, then
something else is configured incorrectly. Perhaps your proxy isn't
properly handling the https stuff. Not sure how to figure that out...I
understand the basic concepts of proxy/reverse proxy, but I have zero
experience actually working with one.

Well, those both use POST requests, so perhaps those aren't being
handled properly. Either that, or I noticed that the time field you
originally noticed the problem with is submitted via ajax (using
XMLHttpRequest), so perhaps those requests aren't working right. I
know from experience ajax can be problematic with things like
cross-site-scripting (XSS), and maybe because of the proxying, it
might be possible that those requests appear to be XSS to the browser
(not sure, just a wild guess). I believe that when you are on the
listings page and you hover the mouse over a show to see the details
tooltip, I think those are done via ajax, too. Do those tooltips work
