I work at Coscend, a cloud and communications software product company. We have built a Web portal-based collaboration platform that we would like to host on five different Windows- and Linux-based servers in different hosting environments that run Web servers. Each of these Windows and Linux servers have a different host name and domain name (and IP address).

Out team would appreciate your guidance on:

(1) Is there a way to implement this Web portal-based platform on these Linux servers without customizing the host name, domain name and IP address for each individual instance?

(2) Is there a way to create some variables using JavaScript for host name and domain name and call them from the different implementations?

(3) Can these JavaScript modules be made portable and re-usable object modules for different environments and instances?

The portal is written in JavaScript that is embedded in HTML5 and padded with CSS3. Other technologies include Flash, Flex. Databases used are PostgreSQL and MySQL.
