title: Access-Control-Allow-Methods and Microsoft Edge, works with Firefox and Chrome
body: <p>I'm using superagent to execute a <code>DELETE</code> call to my WebApi backend. </p>
  
  <p>The pre-flight call says that the <code>Access-Control-Allow-Methods</code> are <code>*, GET, POST, PUT, DELETE, OPTIONS</code>. Using the method <code>DELETE</code> works fine in Firefox and Chrome, but not Edge (maybe the same with IE?). </p>
  
  <p>Im getting this error in my console: </p>
  
  <blockquote>
    <p>SEC7124: Request method DELETE was not present in the Access-Control-Allow-Methods list. </p>
  </blockquote>
  
  <p>The preflight call for it returns the same in dev-tools for Edge as for Chrome and Firefox. The server is running CORS.</p>
