Woah. Are we setting the Expires: http header in our Tor answer based on
how long we think the *payload* will remain valid, and the proxy in the
middle is caching both the payload and the headers for that time?

That's what most caches do with unknown headers: cache them for the same period as the payload.

I've logged Trac ticket #17605 to see if we can tell caches not to cache the X-Your-IP-Address-Is header.
