How does CORS work with authentication?
CORS, or Cross-Origin Resource Sharing, allows web applications to make requests to domains other than their own. When authentication is involved, the server must include specific headers to allow the browser to send credentials.
What headers do I need to set for CORS with credentials?
You need to set the 'Access-Control-Allow-Origin' header to the requesting origin and 'Access-Control-Allow-Credentials' to true.
Can I use CORS with cookies for authentication?
Yes, you can use cookies for authentication with CORS, but ensure that the 'withCredentials' flag is set in your XMLHttpRequest or Fetch API call.
What are the security implications of using CORS with authentication?
Using CORS with authentication can expose your application to risks like CSRF attacks. It's essential to implement proper security measures, such as validating origins and using secure tokens.
