title: Open Graph scraping base URL instead the URL it's given
body: <p>The Facebook OpenGraph debug tool is scraping the wrong page.</p>
  
  <p>If I give it a full URL (pointing to an individual page on my site) that I want it to scrape, instead of scraping that page and finding its meta tags, it scrapes my site's <em>main page</em> and returns those meta tags (which are obviously wrong in this context).</p>
  
  <p>The weird thing is, it will even find and scrape my site's main page even if it's not located at the root of my domain.  For example:<br>
  I want it to scrape <code>http://mydomain.com/myhomepage/specific_page.html</code><br>
  Instead, it scrapes <code>http://mydomain.com/myhomepage/</code></p>
  
  <p>This implies to me that the error must be a setting someplace, either on my site or on my Facebook App settings.  Would the App settings do that?  Redirect to whatever URL is set if a requested URL is a descendent of it?<br>
  The URL I'm requesting is not doing a 302 or anything - I can click the link from the FB debug tool even and it will take me to the appropriate page.</p>
  
  <p>A few notes:</p>
  
  <ul>
  <li><code>specific_page.html</code> is not an actual file, it is routed through index.php using mod_rewrite in Apache's htaccess.  I tried being specific with <code>http://mydomain.com/myhomepage/index.php/specific_page.html</code> and it did not work then either.</li>
  <li>Another SO question led me to believe that the user-agent might be getting redirected if it doesn't allow cookies (as the Facebook web crawler does not) so I opened a fresh browser, disabled cookies, tried again, and I still reached the appropriate page.</li>
  </ul>
