The client_max_body_size directive limits maximum request body size as specified in the “Content-Length” request header. Since chunked transfer encoding support introduced for request body in nginx 1.3.9, the limit instead applies while processing body chunks if the request body is signalled with "Transfer-Encoding: chunked". In HTTP/2 (and upcoming HTTP/3) the limit also applies to the actually processed request body chunks in the corresponding protocols, if the "Content-Length" request header was not specified in a request. -- Sergey Kandaurov _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
