I'm working on a GUI which uses Marmotta. It's built with JS using ajax requests. I'm trying to create a new resource, then show the user the location of the created resource. For this, I use the XHR object and the standard getResponseHeader() method to get the value of the "Location" header. The problem is that in case of CORS requests, the getResponseHeader() method can't reach the "Location" header since it's not a simple response header and it can access non-simple headers only if the response contains the "Access-Control-Expose-Headers" header which lists them. I can't see this header in the response and I can't access the "Location" header.
