--- Comment #2 from Yann Ylavic <ylavic....@gmail.com> --- The interim responses are passed through connection filters only (AP_FTYPE_CONNECTION), so I think that mod_headers does not see them (even with latest 2.4.48), thus the Header directive is ineffective here. I can't find anything about HSTS and interim responses, but for "101 Switching Protocols" in particular I don't think it makes much sense anyway when the protocol is to change to something not HTTP suposedly. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: bugs-unsubscr...@httpd.apache.org For additional commands, e-mail: bugs-h...@httpd.apache.org
