Load balancers should have the possibility to enable or configure persistance for load balancing web applications.
A formal definition of what we need is:
Persistence is a feature that is required by many web applications. Once
a user has interacted with a
particular server all subsequent requests are sent to the same server
thus persisting to that particular server.
It is normally required when the session state is stored locally to the
web server as opposed to a database.
Most load balancers have options to setup persistant connections for a defined amount of time using different sources of information as a means to control it, for example source address, http hash, cookies etc.
Any method is more than welcome, the current load balancers are really useless for balancing dynamic content which need to sustain a client session because that session is constantly lost without the persistance support.
Thanks a lot
