title: Url Shortener redirects to index.html
body: <p>Yes, yet another url shortener written in java, because I wanted my own, and because why not.  Currently everything works, just not they way I want to to.  In short, there is only one servlet mapped to "/" in the entire project.  There are no frameworks involved, or anything fancy, this is just a basic Servlet "project".  on doPost a new shortUrl is created, and you get a JSON response.  On doGet, if the URL is "/*{any_valid_short_url}" then a redirect is sent (below).</p>
  
  <pre><code>response.sendRedirect("longUrlString")
  </code></pre>
  
  <p>The issue I am having is with the index page, when the same doGet is called, I check the requested path, if it is "/" then currently, I use a FileInputStream and stream the index.html page out via response.getOutputStream(), which is pretty hacky in my opinion.  I would like to use a requestDispatcher instead, however when I do try to implement that (below) I get into a re-direct loop, and the servlet container (jetty or tomcat) stack overflow's.</p>
  
  <pre><code>getServletContext().getRequestDispatcher("/index.html").forward(req, res);
  </code></pre>
  
  <p>Is there something that I am mis-understanding about how this is being done?  The project is currently hosted on my github page.  <a href="https://github.com/justinmburrous/ShortUrl" rel="nofollow">https://github.com/justinmburrous/ShortUrl</a></p>
