However, for a Jolokia client library users a cross domain request should be transparently possible regardless the browser in use.
Ideally and the perfect solution would be to automatically detect from the Jolokia-URL whether a cross site access is required, then if CORS is supported or a JSONP fallback should be used, so that this would work transparently without doing any configuration.
For implementation starting points, please refer to
Is there an automatic detection for cross domain requests ?
Automatic degradition to JSONP when CORS is not available ?
