Have facebook scrape a different URL than what was shared

I have a Single Page Application built in ember.js, we have this hosted on AWS S3 and I'm trying to come up with a solution for when someone shares a URL from our site to facebook to have facebook be able to scrape the content on that page properly.

Obviously this won't work at this time because facebook does not support indexing javascript like the google search engine does. So one solution I've seen is to use apache .htaccess to redirect requests from facebook to a server file that can make a barebones html page with the necessary open graph tags like in this post

However since we're on S3 I can't do an apache .htaccess, and from what I've been able to gather from the sparse docs on how their S3 redirect rules work and what they can do I'm not sure if there is a way to do this with that method.

So my question is does facebook or open graph or even just normal meta tags have away of allowing the user to share a url, have facebook use that but follow a link to a server generated file, and then if someone clicks that link actually have it point the user to the real single page application page instead of the server file facebook will use for the scrape data.
