<cors> element should allow circumvention of authorization check for pre-flight request

Original conversation in IBM Cloud Slack workspace at

When CORS is turned on and application security is also turned on, the OPTIONS pre-flight can be prohibited by the application security (401 Unauthorized) unless the application has specifically excluded OPTIONS from being secured. This is seemingly in contravention of the CORS specification because there should be no authentication information on the pre-flight request.

It feels like, when CORS is enabled, the pre-flight request should circumvent the application security so that it can return the pre-flight response.

This decision is in the server's domain rather than the application, which may be pre-packaged and unaware of the serving situation it may be in.

    Thank you for the suggestion. The requirement does have merit, but looking at it with respect to our total backlog of requests we do not see sufficient interest in this enhancement to merit delivery any time in the foreseeable future. Given the unlikelihood that we would deliver this, we are declining the request rather than leaving it in an uncommitted state for an extended period of time. If you would like to discuss this decision further, please contact Graham Charters <>.
