Mistake #1: echo and proxy_pass cannot be used in a single location
since only one content handler (or content generator) is allowed in a
single location, for obvious reasons, so only one of them takes
effect.

Mistake #2: you have to resume the workflow yourself via request
parameters or cookies since this must go across the Lua boundary (and
also machine boundary) since you're doing two separate HTTP requests
and two separate network round trips here.
