What is CORS and how does it affect web security?

CORS stands for Cross-Origin Resource Sharing. It's a security feature that allows or restricts resources on a web page to be requested from another domain outside the domain from which the first resource was served.

Why is CORS important for web applications?

CORS is crucial because it helps prevent malicious websites from accessing sensitive data on another domain. It ensures that only trusted domains can interact with your web application.

Can you give an example of a CORS error?

Sure! A common CORS error occurs when a web application tries to fetch resources from a different origin without the proper headers, resulting in a blocked request.

How can I enable CORS on my server?

To enable CORS, you can set the appropriate headers in your server's response, such as 'Access-Control-Allow-Origin' to specify which domains are allowed to access your resources.
