I have an application server behind nginx that may output chunked  
responses, and would like to use compression for them as I do for  
ordinary responses.

Is that possible with nginx? If it is, is it possible in a way that  
nginx compresses stuff on the fly and sends chunked (compressed)  
responses itself rather than buffering the original response and  
sending a non-chunked response itself? (That would defeat the purpose  
of the chunked responses.)

It does not seem to work. It compresses the payload of the application  
server.
