title: URL routing conflicts for static files in Flask dev server
body: <p>I want to define a url rule with three variable components, like:</p>
  
  <pre><code>@app.route('/&lt;var_1&gt;/&lt;var_2&gt;/&lt;var3&gt;/')
  </code></pre>
  
  <p>But I find that the development server evaluates such rules before trying to match for static files. So anything like:</p>
  
  <pre><code>/static/images/img.jpg
  </code></pre>
  
  <p>will be caught by my url rule, rather than being forwarded to the built-in static file handler. Is there a way to force the development server to match for static files first?</p>
  
  <p>P.S. This is only an issue if the rule has more than two variable components.</p>
