I set proxy\_max\_temp\_file\_size = 0; or proxy\_max\_temp\_file\_size = 20m;  
and download a 30m file,the nginx still wirte a temporary file.  
I see from nginx wiki:  
If file is larger than this size, it will be served synchronously from  
upstream server rather than buffered to disk.  
If proxy\_max\_temp\_file\_size is equal to zero, temporary files usage will  
be disabled.

I understood when the file size over proxy\_max\_temp\_file\_size,it  
shouldn’t write to proxy\_temp\_path.  
But it seem doesn’t work.  
I understand wrong?

I hope somebody can help me and shed some light on what’s going wrong.
