title: Web pages accessible by multiple URLs for SEO reasons
body: <p>I have a bunch of pages with the following structure:</p>
  
  <pre><code>&lt;html&gt;
      &lt;body&gt;
          &lt;div id="summary"&gt;
          &lt;/div&gt;
          &lt;div id="promotions"&gt;
          &lt;/div&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p><img src="https://i.stack.imgur.com/E7Ztn.png" alt="enter image description here"></p>
  
  <p>I want these pages to be accessible by both:</p>
  
  <ul>
  <li>/items/one</li>
  <li>/items/two</li>
  <li>/items/three</li>
  </ul>
  
  <p>And:</p>
  
  <ul>
  <li>/promotional-offers/2014/february/one</li>
  <li>/promotional-offers/2014/february/two</li>
  <li>/promotional-offers/2014/february/three</li>
  </ul>
  
  <p><code>/items/...</code> should just open the page. <code>/promotional-offers/2014/february/...</code> should open the page <code>/items/...</code> and go to the anchor <code>#promotions</code> (scroll down to the appropriate <code>div</code>).</p>
  
  <ul>
  <li>/items/one/#promotions</li>
  <li>/items/two/#promotions</li>
  <li>/items/three/#promotions</li>
  </ul>
  
  <p>I'm not sure though how to set up rewrite rules in <code>web.config</code> to help search engines with indexing my pages and avoid having 'duplicate content'.</p>
