Yes, it's part of Enterprise. The load balancing features work fine, although most people ignore the session replication because it's more trouble than it's worth.
You can run two instances of multiserver in a cluster on the same machine and get the benefits you are after. If you run them on separate machines, you also get the benefits of extra CPU power and hardware redundancy. mxAjax / CFAjax docs and other useful articles: http://www.bifrost.com.au/blog/ 2009/4/16 Matthew Learn <[email protected]>: > > I have read about some of the load balancing features of Cold Fusion, has > anyone used the built in features of CF 8 (this might only be in the > Enterprise version). > > Along those lines, if someone has gotten the built in CF load balancing > working, I was wondering if you would be able to run two CF Servers on the > same machine configured for load balancing?
