CORS Tester

Use this little website to test if a URL is setup correctly to work with CORS.




If your CORS setup is not using a wildcard then this should be a domain that matches your AllowedOrigins


Shareable link:

Results

This URL will only work for specific domains.

What's that mean?

This url can only be loaded by pages that match https://www.quizland.co.uk. If you're trying to load it from a different origin and it's not working, you'll need to change it so the access-control-allow-origin header is set to *.

Headers

These are the response headers received when making the request.
