Why do you think that?
If the problem is nginx buffering when it should not, then the fix should
be on the nginx side. If the problem is something else -- the fastcgi
server or something else doing the buffering -- then time spent changing
nginx is wasted.
Can you find out what is really happening?
For example: change the fastcgi server to listen on a network port;
change nginx to fastcgi_pass to that; and use tcpdump to watch the
traffic involving that port.
Then do a file upload that takes 30 seconds or more.
Does the tcpdump trace show the right amount of traffic going from
nginx to the fastcgi server during that 30 seconds while the upload is
happening? Or does it show no traffic until the upload has completed,
and then lots?
With that information, it may become clear whether the problem can be
fixed in nginx, or whether it must be handled elsewhere.
Good luck with it,
