title: Flask static files getting 404
body: <p>I am building a basic web app with following project structure. The app is  fine but I am getting 404 errors for some of the static files.</p>
  
  <p>I don't have any file like this bootstrap.css.map and not able to find enough docs related to this in flask.</p>
  
  <pre><code>127.0.0.1 - - [09/Feb/2014 22:37:17] "GET /static/css/bootstrap.css.map HTTP/1.1" 404 -
  
  @app.route('/')
  def index():
  print 'in /'
  return send_file('templates/login.html')
  </code></pre>
