Hi ADHTB, this is Riramar from the OWASP Secure Headers Project. How are you doing? Thanks a lot for your contributions on OWASP Secure Headers Project! I have one question about allowall for X-Frame-Options which seems to have the same effect that no X-Frame-Options header. Do you know any reference for this value? I was checking the RFC (https://tools.ietf.org/html/draft-ietf-websec-x-frame-options-01) and there's no mention there.
