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

having fastcgi\_buffers 0 0 and fastcgi\_max\_temp\_file\_size 0 should make  
nginx not buffer. I say in theory because I have no idea whether  
fastcgi\_buffers can actually be set to zero.
