--- Comment #23 from Yann Ylavic <ylavic....@gmail.com> --- > so to sum up: > * If no filter is in place the request will be passed as-is to the upstream > server, regardless whether it is with CL or chunked. Omitting CL (convert to > chunks) in this case would mean that a upstream server is not able to reject > a potentionally to large request body in advance. In 2.4.x, mod_proxy won't send chunked TE unless proxy-sendchunked is set. If the request body is chunked then mod_proxy will (by default) spool it. The cases where the body is streamed (passed as-is) is when there is a CL and either there is no resource filter or the body can be prefetched (<16K and immediately available). > * If a filter is in place and the client has sent a CL, mod_proxy will spool > into memory/on disk, and depending on the filter either send chunks or have > a modified CL to send to the backend. If/after the body is spooled, mod_proxy will always send a CL to the backend since the length is known. Maybe the code is a better explanation here afterwall.. 2.4.x: https://github.com/apache/httpd/blob/2.4.x/modules/proxy/mod_proxy_http.c#L530 trunk: https://github.com/apache/httpd/blob/trunk/modules/proxy/mod_proxy_http.c#L627 -- 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
