Cross Origin Resource Sharing tests

This table points to results from Cross Origin Resource Sharing tests from http://w3c-test.org/webappsec/tests/cors/submitted/opera/staging/

They are downloadable at their W3C dvcs repository.

You can find the CORS specification in two places, WHATWG fetch and W3C CORS. The WHATWG-version is usually a bit more up to date.
