title: Setting Cors For Blob Storage Via Resource Sharing Not Working - "Blocked By Cors Policy"
body: <p>Attempting to run an axios call to get a file results in the following error in console:</p>
  <p>&quot;Access to XMLHttpRequest at 'Request Url' from origin 'Origin Url' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.&quot;</p>

  <p>As seen above, I have set Allowed origin, Allowed headers, and Exposed headers to *.
  I have also set Allowed methods to GET and Max age to 200 (seconds).</p>
  <p>I've setup a .Net Core project which is handling the requests, using Postman I have verified the request is functional. However in my React project due to CORs it is not. Here Are The 2 Requests:</p>
  <p>React Request: (Returns Cors Error)</p>

  <p>Postman Request: (Successful - 200 Response)</p>

  <p>I understand that using * is horrible for security purposes, and I intend to change it once I can confirm basic functionality for the feature I'm trying to implement. That being said how can I setup Azure Blob Storage Cors so I can make axios calls from React to get file data?</p>
