Which cgi module is used on httpd? mod_proxy_fcgi, mod_fcgi?

Did you take a network trace between httpd and the backend (pcap with
wireshark or tcpdump)?
Are the remaining bytes actually sent by httpd or not?

I don't see how (for now) it could depend on the client's side type of
connection (TLS or not).
The dumpio traces show that in both cases the whole content is
received by httpd, so let's see with network traces whether it's been
sent on the other side.
