CORS request not working in Safari

Question

I am making a CORS xhr request. This works fine in chrome, however when I run in safari I get an \'Can not load ---- access not allowed by Access-control-allow-origin\'.

Answer 1

When I query your URL I'm getting back the following Access-Control headers:

Access-Control-Allow-Origin: *
Access-Control-Expose-Headers: Authorization, Cache-Control, Content-Length, Date, Expires, Server, Transfer-Encoding, x-goog-meta-foo1

I suspect it has something to do with your Access-Control headers - either you're leaving something out, or being too specific.

Given that you're actually sending a custom header, you may want to try:

Access-Control-Allow-Headers: *

You could also see if leaving out Access-Control-Expose-Headers makes a difference.

Beyond that, it would actually be helpful to see the actual request / response headers.
