Hi Johnny, If I understand your the first part of your email correctly, you try - with the http server as a front-end, to serve up multiple instance.
E.g. www.site1.org to deliver instance1 (with its specific ports), and www.site2.org to deliver instance2 (with its specific ports). If that is what you want to achieve, please have a look at the various configuration documents of the http server. But in general, serving multiple instances when having set different ports per instance is easily done. You don't need to do anything else beyond the setting of the ports and configuring the http server. Your second part of your email is about serving specific applications to the specific customers through the front end (again if I understand it correctly). For this you do not need to multiple instances. There is a feature called multi-tenancy which enables you to define access to that specific application while sharing the underlying supporting components. In a multi-tenancy setup you can define as a database entry which tenant is associated to the specific application. Truth be told, I haven't seen this in action so I cannot share such experience. If you need to serve data/content to the unknown user (anonymous or open access), you undertake additional steps. But again, you don't need multiple instances for this. Unless other requirements dictate otherwise, of course.
