be a bug in mod_proxy, but to check that I need to intercept the requests generated by the
backend, which I can't do ATM.
It can be done easily, you can get a tcpdump from the frontend or 
backend, eg. on the frontend as root:

tcpdump -nnpi any -s0 -w /tmp/fe-be-dump.pcap -vvv host IP_OF_BACKEND 

After you make the "interesting" request just ctrl+c tcpdump, get the 
file and open it with wireshark.

Hope this helps,
