Session Binding
For any
Content Engine
site that allows visitors to create user profiles and log in, you are
recommended to make use of Apache's
mod_proxy_balancer
for providing sticky sessions
and load balancing.
Be aware that you cannot use application server clustering (that is,
sharing sessions between your application servers) since this requires
that all objects written to the Session
object are
serializable. Currently, this requirement is not met by all
Content Engine
objects, and you therefore need to bind all sessions to one specific
application server. You can either do this in your web server (for
example, Apache's mod_proxy_balancer
, as mentioned
above) or alternatively in the cache server itself, if it supports
this.
