[ZendTo] Troubleshooting Reverse Proxy uploads (cannot drop-off directories)

[Jules]

Kris,

This sounds like you have 2 FQDNs for the same website.

One way of solving that one is split-horizon DNS. So your internal users 
see the serverRoot resolve to the directly-connected internal IP 
address, and external users get the IP of the reverse proxy. And also 
ask yourself if there is any good reason you aren't just sending 
internal users through the reverse proxy as well.

Also, in your reverse proxy, I would make the client_max_body_size a bit 
bigger than the limit you've set as the uploadChunkSize in ZendTo. Else 
you're might get weird things happening due to the proxy rejecting 
upload blocks that you thought it would allow through to ZendTo.

Cheers,
Jules.
