Bug ID: 65361 Summary: 101 Switching Protocols - custom headers are not set Product: Apache httpd-2 Version: 2.4.38 Hardware: PC OS: Linux Status: NEW Severity: normal Priority: P2 Component: mod_proxy_wstunnel Assignee: bugs@httpd.apache.org Reporter: steffen.pro...@mateso.de Target Milestone: --- We are using mod_proxy_wstunnel to reverse proxy WebSocket connections via Apache to our backend. We also use the "Header" directive to always set the Strict-Transport-Security header: Header always set Strict-Transport-Security "max-age=31536000" We now found that certain responses don't contain the custom header. Especially 304 Not Modified doesn't contain it, which is explained in the RFC: https://datatracker.ietf.org/doc/html/rfc2616#section-10.3.5 101 Switching Protocols doesn't contain the header as well for which I couldn't find a sound explanation. Is this a bug or am I missing a good reason why responses with status code 101 shouldn't contain any further headers? -- 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
