title: Axios post with proxy on create-react-app hosting server doesn't work
body: <p>I have following line in my package.json (react app)</p>
  
  <pre><code>"proxy": "http://www.demoapp.com"
  </code></pre>
  
  <p>I'm requesting data using REST-API call</p>
  
  <pre><code>axios.post('/user_data', { // http://www.demoapp.com/user_data
          id:id
      })
      .then((response) =&gt; { 
          console.log(response);
      })
      .catch((error) =&gt; {
  
      });
  </code></pre>
  
  <p>Above code works fine if I use it in my local system, But if I build a project and upload into hosting server proxy doesn't work.</p>
  
  <p>Anyone know the solution? I have checked in github also but not found proper solution.</p>
