title: Redirect to dynamic URL in Spring MVC
body: <p>I want my Spring MVC application to redirect to a dynamic URL (submitted by the user). So if I have code like this,</p>
  
  <pre><code>@RequestMapping("/redirectToSite")
  protected ModelAndView redirect(
      @RequestParam("redir_url") String redirectUrl,
      HttpServletRequest request, 
      HttpServletResponse response) 
  {
      // redirect to redirectUrl here
      return ?
  }
  </code></pre>
  
  <p>what should I write to redirect to the submitted URL? For instance <code>http://mySpringMvcApp/redirectToSite?redir_url=http://www.google.com</code> should redirect to Google.</p>
