Implementing headers compatible with RFC 8297 https://datatracker.ietf.org/doc/html/rfc8297 and specifically want to issue three Link headers in my 200 response - each Link header has a different value as per RFC example:
Link: </style.css>; rel=preload; as=style
Link: </script1.js>; rel=preload; as=script
Link: </script2.js>; rel=preload; as=script
Using IIS 8 I can't just add the HTTP Headers because the UI prevents creating multiple response headers with the same name saying "A header with this name already exists."
Is there a way around this?
