forwarding POST requests to upstream

Does it mean that every POST request is saved to disk before it's
forwarded to a backend? If this is the case then, well, we will just
have to live with that, but this will degrade our performance
dramatically.

And how about the input filter chain you are working on? Will it allow
us to make a GET request in order to determine the backend to which we
will forward the original POST request?

Maybe you can think of another way of choosing the backend based on
what is inside POST body?
