--- Comment #3 from Yann Ylavic <ylavic....@gmail.com> --- What might happen is that the backend responds with 401 without first sending the "100 Continue" interim response, because the auth on the backend happens before the request body is read (it does not need the body). Given the final response, the frontend has to "Connection: close" with the client because the 100-continue is now incomplete (the request body was never read). Adding "Proxy100Continue off" to the frontend configuration should prevent that since the "100 continue" would be handled entirely on the frontend. -- 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
