title: Play Framework 2 URL without port
body: <p>this must be a really easy question to answer but I can't seem to find a solution anywhere. I have a play framework 2 application that I want to put in production on Windows Server 2008. I only have ports 80 8080 and 443 open to the outside.
  I start my play application with this:</p>
  
  <pre><code>play -Dhttp.port=80 "run 80"
  </code></pre>
  
  <p>but I get an error that says that "failed to bind to: /0.0.0.0:80.
  I can do:</p>
  
  <pre><code>play -Dhttp.port=8080 "run 8080"
  </code></pre>
  
  <p>and this works, I can get outside access to my web application by typing <a href="http://sometestingurl.pt:8080/index" rel="nofollow">http://sometestingurl.pt:8080/index</a> but I don't want to have the port number on my URL. How can I do this?</p>
  
  <p>Thanks</p>
