Cookies? There are no cookies in LVS. Persistence is handled by
templates. A template matches the source ip address and protocol,
the source port is ignored. The template determines the affinity of
a matching source to a real server. When a connection is to be scheduled
for a persistent service if a template can be found then the real
server information it holds is used, else a new template is created
that will be used for this and subsequent connections. Templates
are ip_msaq structures and timeouts are handled by the ip_masq code.
That is the ip_masq code removes templates once the timeout expires.
