Hi,
when setting ProxyErrorOverride to "On" to get the httpd-ErrorDocument
instead of the backend-errordoc, httpd is waiting "ProxyTimeout" seconds
to respond to the client, even though the response is already read from
backend server.
The request/response is hanging somewhere in
module/proxy/mod_proxy_http
-> ap_proxy_http_process_response
-> ap_discard_request_body(backend->r) (modules/http/http_filters)
before timing out with "ProxyTimeout".
ProxyErrorOverride Directive:
http://httpd.apache.org/docs/current/mod/mod_proxy.html#proxyerroroverride
Best regards,
Zisis
