title: How do I share content from a Facebook Page Tab's internal page?
body: <p>I'm trying to share content that is on a Page Tab's internal page. Each item on this page has a Like button and I'd like to redirect the user to the page and scroll via JS to the item. Preferably, I'd like to not disclose the site's real url. In other words, to share something like this: <a href="https://www.facebook.com/pages/PAGENAME/PAGENUMBER?sk=app_PAGETABNUMBER&amp;app_data=5" rel="nofollow">https://www.facebook.com/pages/PAGENAME/PAGENUMBER?sk=app_PAGETABNUMBER&amp;app_data=5</a></p>
  
  <p>The problem is when I try to share the url above, Facebook doesn't take into account the OG tags. Any suggestions? Thanks!</p>
  
  <p>Edit 1: when I put an url like the one above on Debugger, it says "Facebook URLs aren't scrapable by this Debugger", so I guess it isn't able to find the og tags. </p>
  
  <p>Edit 2: if I put the site's real url in the data-href of the Like button and in the initial Page Tab page I get the app_data to do a redirect to the internal page with the og tags (where og:url points to the url mentioned above), Facebook ignores the og tags. In the Debugger, it says "Error parsing input URL, no data was scraped."</p>
  
  <p>Edit 3: could only get it to work by sharing the real site's url. When a user visits the link, I redirect him to the url above. If the user agent has facebook in its name, I neither load the PHP SDK nor do the redirect, in order to let it retrieve the og tags.</p>
