How to get the origin URL from a “doPost” request

Question

I've been trying to identify the origin of a POST request made to a Google Apps Script doPost() content service;

function doPost(request) {
   // Something like this:
   var originURL = request.headers.URL; // http://myurl.com

}

Since I have published it ("Deploy as web app"), to 'Anyone, even anonymous', it has the following header:

access-control-allow-origin: *

So I want to control it's access in my code.

Is it possible?

We can not use direct post method in other aplication but you can use URL parameters passing try following. Publishing script makes sure you have updated version and copy /exec link. you can pass URL parameters like https://script../../exec?=para1=1012D.
