Theoretically you are able to offload SSL at haproxy, and pass raw, unencrypted
SPDY to the backend.
I doubt however that this has been done before, and nginx most certainly
doesn't accept unencrypted SPDY traffic, so yes, tcp mode will be the only
option for now.

I'd like to enable SPDY protocol using nginx. For this to work, do the
frontend haproxy load balancers need to operate in tcp mode only? Or, can
they use http mode to pass the SPDY requests to nginx?
