How do I make a single web application available under multiple contexts?

Issue

• We would like to deploy a single war and have the application available under the root context www.domain.com and also under a named context www.domain.com/app/.

• How to rewrite the old URL to the new one internally in EAP 6.x ?

• I want to keep the context name but to have a separate friendly name for the URL access. Is there any Jboss parameter that I could use so as to achieve this goal ?

• Is it possible to access the application on multiple contexts as below:
  http://10.10.10.10:8080/myApp and http://10.10.10.10:8080/app/myApp
