Hi, given
client --(tcp)-->nginx --(fcgi)-->fcgi server --(tcp)--> back-end server
if the client initiates a TCP disconnect, is there a way for NGINX to carry out the termination to the fcgi server?
Or if the back-end server disconnects, how can the fcgi server communicate the disconnect all the way to nginx and the client?

From what I observed, a client could send a TCP FIN, but NGINX will keep the FCGX connection up.
Thank you.
