问题
I've created a single-page app. All deep links are in the form of mysite.com/#!/entry_title. This allows Google (and Facebook) to check an alternate URL for the content of that page.
I've setup a server-side check to determine if Google or Facebook is looking for the HTML snapshot of this page. If so, it sends a different header containing the necessary Facebook og meta tags.
Here's the problem. If I paste one of my URLs (mysite.com/#!/entry_title) into my status box the URL that gets displayed is the HTML snapshot URL (mysite.com/?_escaped_fragment_/entry_title).
The og:url meta tag on the HTML snapshot page is set to mysite.com/#!/entry_title.
How can I make the Sharer display the mysite.com/#!/entry_title version of the URL instead of the HTML snapshot version?
Thanks in advance!

I've figured this out and thought I'd post the answer for others.
The trick is to setup a redirect for Google/Facebook to go to a prettier URL. So any URL in the form of
mysite.com/?_escaped_fragment_/entry_title
gets redirected to something prettier like
mysite.com/view/entry_title
When someone shares one of my dynamic URLs, Facebook requests the _escaped_fragment_ version of the page, and gets redirected to my prettier URL (mysite.com/view/entry_title), which is what gets shown in the Facebook post.
To make sure people always share my dynamic URL I've setup a javascript redirect on the mysite.com/view/entry_title pages to redirect back to the mysite.com/#!/entry_title pages.
While this doesn't show the dynamic URL in the Facebook Share, it shows a prettier URL than the _escaped_fragment_ version and forces people back to the dynamic URL that I want people to share.
