Whatever the reason for forcing the connection closed -- it only closes when
the scheme changes. Redirecting to a different host or port when using a
“scheme less” URI allows the connection to be kept open.
listen http
bind :8000
http-request redirect location //127.0.0.2:8001/redir

Maybe that will be useful to Ciprian to make the redirect to a new hostname but
keep the connection to the old host open if that’s what is needed.
