Cross-Origin Resource Sharing (CORS) Issues in Nginx

The incident type pertains to the challenges arising from making cross-origin resource sharing (CORS) requests to an Nginx web server. CORS serves as a security measure in web browsers, aiming to prevent unauthorized access to resources across domains. However, when Nginx is not properly configured to allow CORS requests, browsers will block these requests, resulting in errors. This playbook helps resolve CORS errors in Nginx by configuring the server to allow cross-origin requests.
