Gzip filter on streaming responses

I did some investigation and the gzip filter will only activate if there
is a Content-Length header with valid length.

Is there any way of deflating streaming responses from the nginx push
stream module? Where is there isn’t a known content length, but
potential for thousands of messages to be transferred?

Have you tried?

       gzip on;
       gzip_min_length 0;

This is not true. With Content-Length present gzip filter is able
to more effectively allocate buffers (or skip responses as per
gzip_min_length), but it isn’t limited to responses with
Content-Length present.

As long as push stream module does things correctly it should
work, but that’s the question more about (3rd party) push stream
module, not gzip filter.

That makes much more sense. Thank you for clarifying how the gzip filter
works.

There is a patch forthcoming for the push stream module that adds the
necessary information to get gzip working.
