Setting to turn off buffering of file uploads to proxy backends?

[Ezra Zygmuntowicz]

Hi-

	Is there any way to get a config setting in nginx to turn off  
buffering of file uploads to proxied backeds? I woudl really like to  
be able to use mongrel_upload_progress to do upload progress bars in  
rails applications. Right now there seems to not be a way to turn off  
buffering of file uploads when the handler is a proxy backend.

	Is there a way to turn this off? Coudl you please add one? Apache2.2  
and lighty both support non buffered file uploads to proxied backends  
and it would be great if nginx could support this as well.

Thank You-
