title: Making axios requests are blocked by cors
body: <p>I'm trying to make an axios get-request from a spa app to a python falcon server that should be all set for CORS requests. I'm providing the following headers to my request:</p>
  
  <pre><code>const getHeaders = {
    headers: {
      'Access-Control-Expose-Headers': 'X-json',
      'Access-Control-Allow-Headers': '*',
      'Access-Control-Allow-Origin': '*',
      'Access-Control-Request-Method': 'get',
      'Access-Control-Request-Headers': 'X-custom-header',
      'Content-Type': 'application/json',
      Accept: 'application/json',
    },
  };
  </code></pre>
  
  <p>There's a lot of stuff there because I've scavenged through a bunch of threads already trying to find a fix, but nothing seems to work for me. </p>
  
  <p>I've managed to make requests to this same server before using JavaScripts fetch api and disabling cors on the browser with a chrome plugin.</p>
  
  <p>I've hit a bit of a brick wall now, any help is appreciated. I'm using webpack-dev-server for development, but I've also got an express setup for production where I've tried to set these same headers with use on express, but the problem repeats.</p>
  
  <p>Thanks!</p>
