From a tutorial here:
http://ankurm.com/blog/api/using-localhost-for-facebook-app-development/1091/
I tried to set up a Local development Area for my Facebook
When I wrote that tutorial at that time port was allowed in app domain. And I actually able to run app with 81 port (wamp server). Now it looks that facebook is not allowing port in url. You can use localhost in app domain.
I will update information as soon as possible. I am trying to find out solution.
A temporary solution is use localtunnel http://progrium.com/localtunnel/
