Nginx Proxy redirect to clients when upstreams are busy

[Prasanna Khanapur]

Hi maxim,
Thanks a lot.  Could give some inputs on how to export variable from inside
my module? I'm kind of new to nginx variable stuff. Do I need it to use
other modules like lua,resty? I would prefer to avoid them if possible.
Regards
