Manytimes we need to host multiple websites/applications on a single host - e.g., say a wordpress (php) blog with a play app or 2 play apps on a single host. One of the simplest way to achieve this is to use apache as a frontend proxy routing traffic back to the right application based on domain name.
Post 2.5.x release, older approach of having Global objects to access configuration parameters available in application.conf is no longer recommended. Instead, it is advised now to use dependency injection to access these.
