Emulate cross-site requests in localhost

Question

Is there a way to make cross-site requests in the localhost? To emulate a different domain? How do you make an application, for example to do JSON-P or CORS and test it in your local machine without having an actual domain?

I am using NodeJS and WebStorm.

Thank you.

Assuming you can access your site from both 127.0.0.1 and localhost, load the page via localhost and have that page access http://127.0.0.1. I can't guarantee this triggers cross-origin in all cases, but it was working for me with iframes.
