Q: How can cross-origin requests (CORS) be implemented?
A: Cross-origin requests can be implemented using the following methods:
- JSONP (JSON with Padding): A technique that works by loading a script from a different domain, bypassing the same-origin policy.
- CORS (Cross-Origin Resource Sharing): A standard mechanism that allows servers to specify who can access their resources. It involves sending HTTP headers like
Access-Control-Allow-Origin. - Nginx Proxy: A server-side solution where a reverse proxy (like Nginx) forwards requests to the target server, effectively hiding the cross-origin nature of the request.
