When I open the app again, for a brief moment I see where I used to be (at that scrolled location on that page), but then the app "reloads" and I get scro...
I'm implementing something like a cache, which works like this: If a new value for the given key arrives from some external process, store that value, and remember the time when this value arrived.

It is said that the web servers' clocks must be identical for the Expires and Cache-Control headers to work? Why is that? Can't they be off by 1 second or a few minutes? If the cache is supposed to be good for 1 year, then won't a time difference of a few minutes or even a few hours not matter on one or some of the web servers? In ht...
