Session Binding

On an ECE site that uses profiles (so that users can be created on the page andthey can log in) and VCE sites, Apache is really helpful in providing sticky sessions and load balancing with its excellent mod_proxy_balancer module.

Please be advised that you cannot use the application server clustering (i.e. sharing a session between the application servers) as these, regardless of their backend or implementation, require that all objects written to the Session object are serializable. Currently, not all ECE objects fulfil this requirement and you therefore need to bind all sessions to a particular back end (i.e. application server). This binding can either be done in the web servers (as mentioned in the paragraph above) or on some cache servers, such as Oracle Web Cache .
