title: Facebook Share URL having hash
body: <p>My single page website has some products, and product details appear as simple pop-up when clicked. For each product there is Facebook share. But when I Facebook-share the url say <code>www.example.com#product1</code> in the shared url the <code>#product1</code> get stripped.</p>
  
  <pre><code>FB.ui({
    method: 'share',
    href: 'http://example.com/#product1',
  }, function(response){});
  </code></pre>
  
  <p>When I share it comes as only <a href="http://example.com/" rel="noreferrer">http://example.com/</a>   , not <a href="http://example.com/#product1" rel="noreferrer">http://example.com/#product1</a>.   I want the full URL to be shared like <a href="http://example.com/#product1" rel="noreferrer">http://example.com/#product1</a>. Its getting stripped off somehow.</p>
  
  <p>How to avoid this?</p>
