title: How to forward to an external url?
body: <p>My Spring based app is running under <a href="http://localhost" rel="nofollow noreferrer">http://localhost</a>. Another app is running under <a href="http://localhost:88" rel="nofollow noreferrer">http://localhost:88</a>. I need to achieve the following: when a user opens <a href="http://localhost/page" rel="nofollow noreferrer">http://localhost/page</a>, a content of <a href="http://localhost:88/content" rel="nofollow noreferrer">http://localhost:88/content</a> should be shown.</p>
  
  <p>I've supposed, that I should use forwarding, like shown bellow:</p>
  
  <pre><code>@RequestMapping("/page")
  public String handleUriPage() {
      return "forward:http://localhost:88/content";
  }
  </code></pre>
  
  <p>but seems like forwarding to an external URL doesn't work. </p>
  
  <p>How can I achieve this behaviour with Spring?</p>
