Unfortunately a lot of these sites have hard-coded resources with the

view), and because the close behaviour of HAProxy, we end up with a
lot of short-lived connections. (This is not so much a load issue, as
it is a page load latency issue due to the TCP connection
establishment overhead.)
I didn't think about that case, it definitely makes sense. In fact I
mostly focused on first redirection without thinking about systematic
redirection caused by a migration (for example). Now I'm starting to
think that we should never close by default and that we should change
this behaviour as it's counter-intuitive.
I don't know what others think.
I agree; in a full keep-alive world, we should not try to close "by
default", but let
the actual keep-alive code do its job.
But if we do remove those conditions, I guess we break a number of "old
assumptions"
and we will hit new code paths, so there is a potential for bugs :)
