Facebook app domain name when using localhost

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 app. But when I put "http://localhost:85/my_app/" as my domain name, Facebook says

App Domains: "http://localhost:85/app-name/" should not contain protocol information.

Also when I put "localhost:85/my_app/" as my domain name, I get the error:

App Domains: localhost:85/my_app/ is not a valid domain.

It seems like the protocol has been changed.

Here is my solution (I tested on 3rd April 2015 and it works well):

In Settings -> Basic tab

1. App Domain: localhost
2. Click "+Add Platform" and choose "Website"
3. Site URL: http://localhost:<port>/ (<port> is your port number)
4. Save Changes

My solution:

1. Leave App Domains empty
2. (Products) Facebook login > Settings
3. Add http://localhost:85/my_app/ to Valid OAuth redirect URIs box
4. Save Changes

1. Leave App Domains empty
2. Go to Website with Facebook Login
3. Add http://localhost:port_number/
4. Save changes and try again. For more information visit
