HTTP response header

X-Redirect-By header allows users to find what component is responsible a redirect. Every system that sends a redirect and/or has a method in place for sending redirects should prefix that redirect. Right before the location header, there should be an X-Redirect-By header with an identifier as its value. This identifier should clearly identify which piece of software performed the redirect.
