how to turn off fastcgi_buffer

[jpu]

thx in advance first.

i need to turn off the fastcgi_buffer so that my php application could
flush content directly to the client. i googled this topic but nothing
really meanning for.
i tried to set fastcgi_buffer_size to 0, or very small like 10, which
led to an access error.
is there any way that i can turn off the fastcgi buffer functionality so
that i can write directly to the client, like apache did?

thx again
