I belive setting r-\>header\_only here is wrong aproach. At least  
it breaks addition filter module for such responses.

Also you probably want to consider doubled last chunk for stale  
responses as fixed here:

Hello Maxim,

> [(bug?)Timeout when proxy-pass 0 byte file](http://nginx.org/pipermail/nginx/2009-October/015789.html)

You are right, this will break addition filter module.

Your patch works as expected, I wonder why it wasn’t applied in the  
first  
place?

Anyway, I modified your patch a little to avoid unnessesary call to  
ngx\_pcalloc. Hopefully Igor will include this in nginx-0.8.32 😉
