title: How to selectively allow only a few methods to be accessed concurrently using flask?
body: <p>I am using Flask + Python for exposing few API(s). Currently, I have made flask as multi-threaded by specifying </p>
  
  <pre><code>app.run(threaded=True)
  </code></pre>
  
  <p>But, my requirement is that, I want all "GET" methods to be handled in parallel, whereas the POST, PUT or DELETE methods should be queued.</p>
  
  <p>Is there a way to achieve this using Flask and Python?</p>
