What are the differences in how browsers handle CORS credentials?

Different browsers have varying implementations of CORS, especially regarding credentials. For instance, Chrome and Firefox generally follow the same standards, but Safari has stricter rules. Would you like to know more about a specific browser?

Yes, can you explain how Safari handles CORS credentials?

Safari requires that the server explicitly allows credentials by including the 'Access-Control-Allow-Credentials' header. If this header is not present, Safari will not include credentials in the request.

What about Chrome and Firefox?

Both Chrome and Firefox support credentials in CORS requests as long as the server sends the appropriate headers. They are more lenient compared to Safari, allowing for a smoother experience with cross-origin requests.

Are there any common issues developers face with CORS?

Yes, common issues include misconfigured headers, especially forgetting to set 'Access-Control-Allow-Origin' or 'Access-Control-Allow-Credentials'. These can lead to failed requests and confusion.
