How to deploy a portal under a custom context in EPP 5?

Issue

I would like to know how to perform URL rewrite for the EPP. For example, the default EPP URL is http://server.com/portal/public/classic

Suppose I create a new portal called "MyPortal". Then, the URL would be http://server.com/portal/public/MyPortal. And, suppose I have a "Support" page in "MyPortal", then the URL would be http://server.com/portal/public/MyPortal/support.

So, how do I set it in such a way that the URL of "MyPortal" is just http://server.com and the URL for the "Support" page is http://server.com/support ?

Can this be configured in the EPP?
