title: asp.net mvc + detect hashtag change
body: <p>When I try to detect hashtag change in url, for example:</p>
  
  <p><code>http://localhost:54345/Shop/Catalog?cg=9#3221</code></p>
  
  <p>to</p>
  
  <p><code>http://localhost:54345/Shop/Product#1241</code></p>
  
  <p>Jquery hashchange method does not fire.</p>
  
  <pre><code>$(window).on('hashchange', function (e) {
      //....
  })
  </code></pre>
  
  <p>If the hashtag changes between Catalog action, then it detects. Ex:</p>
  
  <p><code>http://localhost:54345/Shop/Catalog?cg=9#3221</code></p>
  
  <p><code>http://localhost:54345/Shop/Catalog?cg=9#2453</code></p>
  
  <p>So my question is, hashtag detection is not possible between different requests? or different ASP.NET MVC Actions?</p>
