Once you return 307 redirect to a client - it's up to a client to 
decide what to do.

If you want nginx to pass requests to a next upstream server, just
leave proxy_next_upstream as set by default to "error timeout".  
It works for all request methods.

See here for details:
http://nginx.org/r/proxy_next_upstream
