title: Block an IP address from accessing my Flask app on Heroku?
body: <p>I've got an IP address that I need to block from my website. Running a Flask app on Heroku, and I'm seeing 50 requests per second on my server, and that definitely shouldn't be happening. </p>
  
  <p>I'm familiar with using htaccess on an Apache server, is there anything similar here (Gunicorn server)?</p>
