title: Flask change the server header
body: <p>I've made a simple flask application:</p>
  
  <pre><code>Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  GET / HTTP/1.1
  host:google.be
  
  HTTP/1.0 404 NOT FOUND
  Content-Type: text/html
  Content-Length: 233
  Server: Werkzeug/0.9.6 Python/2.7.6
  Date: Mon, 08 Dec 2014 19:15:43 GMT
  
  &lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"&gt;
  &lt;title&gt;404 Not Found&lt;/title&gt;
  &lt;h1&gt;Not Found&lt;/h1&gt;
  &lt;p&gt;The requested URL was not found on the server.  If you entered the URL manually please check your spelling and try again.&lt;/p&gt;
  Connection closed by foreign host.
  </code></pre>
  
  <p>One of the things I would like the change is the server header which at the moment is set as <code>Werkzeug/0.9.6 Python/2.7.6</code> to something my own chosing. But I can't seem to find anything in the documentation on how to do this.</p>
