What if the connection works in both cases, but the results are
different? I would guess it's up to the application to know if the
connection should be restarted.

An example for this (although this is a short-life connection) is that
you can directly access PDF of the ACM library via a proxy while you end
up on a webpage asking you to login if you don't use the proxy. I guess
there could be similar examples -- but maybe it's not that important,
don't know.
