CORS Guide
CORS (Cross-Origin Resource Sharing) is a browser security feature that restricts HTTP requests made from scripts on one domain to resources on another domain. Servers must include specific HTTP headers to allow cross-origin access. Without proper CORS headers, browsers will block cross-origin requests.
