I have a vague recollection that OWA uses a nasty form of
authentication which *requires* that each client's end-to-end
connection to the backend be long-lived, and only used by that one
client (as the auth is done in the first few packets and not
repeated). I don't know how you'd configure that in nginx.

I may be wrong about it, however. I've never tried Nginx in front of
OWA myself. This question comes up on the HAProxy list sometimes, and
it seems solvable by HAP users.
