Cliff,

Thank you and Francis for your quick and detailed responses.

Even though the HTTPS redirect was disabled, the application itself
still sends a redirect to /home. For example, if you type in
http://my.domain.com you were successfully redirected to
https://my.domain.com/home. That initial redirect was happening and that
is where the error 310 would occur, at the https://my.domain.com/home
level.

I see that Francis is in agreement with you that the proxy_pass
directive is being negated by the permanent rewrite. Just for my
edification, would you (or anyone else who would like to take a stab at
it) mind confirming that if I remove the proxy_pass directive, I will
still be able to achieve load balancing between the two upstream
servers? If you could explain how load balancing works without that
directive so I have a clearer understanding, I'd be even happier! I have
searched the wiki and my Nginx book, but I'm either missing it, or this
specific scenario is not addressed.

Cheers,

Matt
