ColdFusion sessions are unique to a single server. While session replication exists, it is a very poor choice for production applications due to the serialization time required. 

Many ColdFusion applications were developed with a single server and a single session reference. As an application grows in popularity, it exists the need to have multiple application servers. When this happens, the choice is to either use a sticky-session load balancer strategy which is not optimal as it puts a requirement on upstream architecture to make quality decisions, or the application must be rewritten to no longer use sessions.

A very desirable feature to help ColdFusion applications scale without requiring tricky load balancing strategy would be the ability to move the session to an external provider, such as ehCache or MongoDB. Care must be taken to expire the session as per the requirements of the ColdFusion application (session timeout) and not evict sessions prematurely.

This option should be configurable in the CF Admin and also in Application.cfc.

I should clarify that I meant the identical bug had 10 votes on it, not "against it". They were all upvotes. :-)

We are providing "Redis" for the external session storage, this can be set through the Administrator. There is no App level setting provided as of now. (Comment added from ex-user id:prk)
