* more robust method of obtaining URL * decouple performance logging from providers (mostly) * ignore fake XHR object which jQuery returns for JSONP requests * guard for CORS requests - apparently Chrome refuses to return certain information even with an Allow-Origin: * response header. * Resource Timing is limited to 150 results, which causes fake misses in debug mode. There is an API to increase the limit but it is not implemented in Chrome. I am calling it nevertheless, maybe IE understands it (it is present in the MSDN docs at least). This seems to work for AJAX, CORS, JSONP, image AJAX; CORS requests return 0 for a lot of values, per spec a Timing-Allow-Origin: * header might help that.
