I've read through the caching docs, and "Things Caches Do", but I'm still not clear on something, so here I am.
Suppose I signal Heroku to cache a page for an hour (setting the 'Cache-Control' header to 'public, max-age=3600'). Alice visits the page at noon, and Heroku stashes it in Varnish to expire at 1 p.m. It's also cached in Alice's browser until 1 p.m., so that if she requests it again before then, the request won't even reach Heroku. Bob visits the same page at 12:30. Heroku still has it in Varnish, so it returns it from there, and it's cached in Bob's browser. My question is, when will Bob's browser expire it? At 1 p.m. (the time my app told Heroku/Varnish it was good until), or 1:30 (one hour from the time Bob received it)?
