What is CORS and how does it work in browsers?

CORS stands for Cross-Origin Resource Sharing. It's a security feature implemented in browsers that allows or restricts web pages from making requests to a different domain than the one that served the web page.

Why is CORS important for web security?

CORS is important because it helps prevent malicious websites from accessing sensitive data on another domain. It ensures that only authorized domains can interact with resources.

How can I enable CORS on my server?

To enable CORS on your server, you need to set the appropriate headers in your server's response. For example, you can add the 'Access-Control-Allow-Origin' header to specify which domains are allowed to access your resources.

Are there any common issues with CORS?

Yes, common issues include misconfigured headers, preflight request failures, and browser-specific CORS policies that can lead to unexpected behavior.
