I heard the following about flow of "master/bakcup" sync (piranha + dr ):
Once a connection is established, the master sync daemon (on the active
director) sends data to the backup sync daemon (on the backup director).
The backup director is then aware of an established connection. If the
primary director fails, the backup will take over and still forward packets
from an established connection to the right reral server.
This works fine on long lasting connections (interactive sessions like FTP,
telnet, SSH and so on) but doesn't on short connections (http without
keepalive for example).
Is it true ? if is true I think the better way to solve this is implement
some solution like conntrack-tools (netfilter).
