Directly requires configuring secure response headers to eliminate the insecure setting that enables malicious redirects.
Enforces validated information flow rules on redirect targets so untrusted destinations cannot be accepted.
Requires validation of redirect-related inputs and parameters before they are reflected in response headers.
