3scale - Setting up CORS for IE11

Solution Unverified - Updated -

Issue

  • We are having some difficulties with some pre-flight calls, but only if we use the browser "Internet Explorer 11", in fact with other browsers (chrome, firefox) everything works correctly.
  • The problem is that although the ALLOW_METHODS headers are enabled on the 3scale CORS policies, we still receive the a CORS error, as if it were not present.
