Scott,
John is right, the way to do this is to use either heartbeat or
keepalive and fail over a VIP to a secondary machine in case the first
has issues. Make sure your haproxy files are identical and then test
the failover.
We use heartbeat for one of our clients and so far any time I have had
to either fail it over or it failed over on its own, we only lost 1 - 2
packets.
If your web servers require the visitors to be pinned to that system for
application reasons, make sure you have cookies setup in haproxy so that
when it fails over, the secondary haproxy server knows where to send the
visitor.

Hi All
I am using haproxy to load balance/failover on a couple of my dev
HTTP servers and it works really well.
I would like to introduce hardware redundancy for the haproxy server,
is this possible with the software?
Best Regards
