Forwarding Requests to Multiple Upstream Servers?

[Sven C. Koehler]

Hello,

I am wondering whether it's possible from within an nginx module to
forward a request to multiple upstream servers....  AFAIU nginx's
existing infrastructure does normally only support sending requests to
one upstream server.  In my example I'd like to update data that resides
on multiple servers if it's a POST request and want to send back only the
response of the first upstream server.

Best,
