What are CORS credentials issues and how can I fix them?

CORS credentials issues occur when a web application tries to make a request to a different domain and the server doesn't allow it. This often happens when cookies or HTTP authentication are involved.

Why am I getting a 'CORS policy' error in my browser?

The 'CORS policy' error usually indicates that the server's response does not include the necessary headers to allow cross-origin requests. You need to ensure that the server is configured to send the correct CORS headers.

How can I configure my server to allow CORS?

You can configure your server by adding the Access-Control-Allow-Origin header to your responses. If you want to allow credentials, also include Access-Control-Allow-Credentials: true.

What if I don't control the server?

If you don't control the server, you can use a proxy server to make the request on your behalf, or you can contact the server's administrator to request CORS support.
