Hi,

We are using nginx 0.7.67, and we need to filter a specific error, and  
match it with proxy\_next\_upstream.  
The error we need is when a client send a Connection Reset. I believe  
nginx filter it with “proxy\_next\_upstream error” along with all the  
others connection errors. For ours application the reset error must be  
the only one filtered and then the nginx would use proxy\_next\_upstream  
to send the request to another machine.

Is there a way to do such filter in nginx configuration?

Thanx
