Creating One-way connections or Dont wait for upstream

After or as the connection is closed I would like the data to work internal 
within nginx as normal selecting an upstream proxying it, if the upstream 
timeouts or has an error still be able to use nginx_next_upstream.

If you can (force) close the connection from client side then you can try 
proxy_ignore_client_abort setting ( 
http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_ignore_client_abort 
 ) - which will make nginx to complete the request to upstream.

The other approach (more options to "program" nginx) approach could be to 
use something like Echo module ( http://wiki.nginx.org/HttpEchoModule ) from 
http://openresty.org/
