Hi, We are using Apache 2.2.29 in production with mod_perl and mod_proxy (we're acting as a reverse proxy) and are experiencing a problem with proxying responses from the back end server that don't include a response phrase being turned into a 500 error by Apache when it proxies to the client. The client is using a custom response code of 320 and is not including a response phrase in their status line. This sounds almost identical to an old bug that was fixed (or supposedly fixed) a very long time ago:
https://bz.apache.org/bugzilla/show_bug.cgi?id=44995 In our mod_perl application if we modify the status line read from the backend server to include a response phrase then this avoids the bug. E.g., things are ok if we do something like this when the status line doesn't contain a response phrase. $r->status_line($r->status . ' OK'); Does anyone have any experience with this or should I file a new bug with Apache? Here is some diag info from the httpd binary: Loaded Modules: core_module (static) authn_file_module (static) authn_default_module (static) authz_host_module (static) authz_groupfile_module (static) authz_user_module (static) authz_default_module (static) auth_basic_module (static) file_cache_module (static) cache_module (static) disk_cache_module (static) reqtimeout_module (static) filter_module (static) deflate_module (static) log_config_module (static) env_module (static) headers_module (static) setenvif_module (static) version_module (static) proxy_module (static) proxy_http_module (static) proxy_scgi_module (static) proxy_ajp_module (static) proxy_balancer_module (static) ssl_module (static) mpm_prefork_module (static) http_module (static) mime_module (static) status_module (static) actions_module (static) alias_module (static) so_module (static) Server version: Apache/2.2.29 (Unix) Server built: Oct 17 2014 13:47:09 Server's Module Magic Number: 20051115:36 Server loaded: APR 1.5.1, APR-Util 1.5.3 Compiled using: APR 1.5.1, APR-Util 1.5.3 Architecture: 32-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/var/httpd" -D SUEXEC_BIN="/var/httpd/bin/suexec" -D DEFAULT_PIDLOG="logs/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="logs/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="conf/mime.types" -D SERVER_CONFIG_FILE="conf/httpd.conf" Thanks, Adam
