That still wouldn't tell you though if the caching was time-limited or otherwise.
You can't check the header for that, then? As it's image-specific, which isn't tied to header info on cache expiry, I guess? You don't need very special tools for that, anyhow. The one I'm thinking of (the 4-letter acronym) is pretty all-purpose but maybe can't look into that, either (if I ever think of its name I'll look it up again just to see what its limitations are).
I have wondered, when one deletes a post, if it is actually deleted, or only marked as deleted and then no longer shown.
I think (and this is just a feeling/instinct I've always had; no other basis) they think it's deleted but it's not. So the latter, basically.
There's no undelete button because a) they think it's gone, honestly and b) even if it wasn't it's a Cost thing - mainly it'd mean extra churn on servers to restore things (we'd probably all do it at least once in a while for Reasons, even just silly ones) so maybe not something they'd implement even if they could.
Pure speculation on my part of course, on all of it.
