title: Problem sharing content from "private" site on facebook
body: <p>I have a website that you can only access after login.</p>
  
  <p>I want to be able to share some products on it, but when I click the share button, instead of sharing that particular item, it shares the the content for the main site.</p>
  
  <p>It's like this, an example:</p>
  
  <p>Main Site: www.xyz.com
  Main site title: xyz.com
  Main site description: site xyz</p>
  
  <p>Product Site: www.xyz.com/product_b.php
  Product page title: Product B
  Product page description: check out this amazing product</p>
  
  <p>When I click the share button on the product page, instead of sharing the product information, it shares the main site information... I guess it's related to being a private site...</p>
  
  <p>I'm using addthis.com buttons to do it, but it's the same when I try to do it directly on facebook... </p>
  
  <p>any ideas on how to solve this?</p>
  
  <p>Thanks,
  Luis</p>
