title: How to read querystring that contains a # in ASP.NET MVC?
body: <p>I have a page that is using AngularJS for the routes and ASP.NET MVC as a backend.</p>
  
  <p>When some of my users send a request like the following:</p>
  
  <pre><code>http://mysite/myApp/Accounts/Login?ReturnUrl=%2fmyApp%2f#/myspa1
  </code></pre>
  
  <p>I want them to login first and then be redirected to ASP.NET MVC to redirect them to the appropiate angular route:</p>
  
  <p>Unfortunately in the ASP.NET MVC controller I cannot see any value passed after the <code>#</code> sign using <code>Request.QueryString["ReturnUrl"]</code>.</p>
  
  <p>Any idea how can I solve this issue?</p>
