What is CORS, and how do you configure it in a Flask/Django application?

Cross-Origin Resource Sharing (CORS) is a browser security mechanism that lets servers specify which domains—different from their own—are allowed to access resources, enforcing the same-origin policy via HTTP headers like Access-Control-Allow-Origin and handling “preflight” OPTIONS requests for safety.

In your Full Stack Python Course, understanding CORS is key when your front-end and back-end run on different origins. CORS prevents malicious sites from reading sensitive data while still allowing real communication when configured correctly.

To handle credentials, use

Configuring CORS in Django
Use the django-cors-headers package. It adds the necessary headers to HTTP responses so your browser can allow cross-origin requests—this is essential especially when working with API views or front-end frameworks.

In your Full Stack Python Course, you’ll practice setting up these tools, catching CORS-related errors, and learning how to whitelist specific front-end origins while securing your back-end. Also, I-Hub Talent supports you through this learning journey—our courses include hands-on projects, expert guidance, and remedies for common CORS challenges you’ll encounter as Educational Students coding full-stack applications.
