ngx.say and gzip

amnon.david

The lack of questions on this issue both in this list and on the web seem to indicate that perhaps I'm missing something basic here, but anyway:

I have an nginx+openresty server that sends out JSON replies to clients that query it. To conserve bandwidth, I wish to compress these replies which are returned via ngx.say. The nginx.conf file seems to be configured correctly for this (gzip is on, gzip_types matching the content_by_lua type etc.) yet when the server is queried, the reply content is not returned compressed. I also have PHP connected to the same server and verified that requests to the PHP scripts do return compressed. Since I assume it is nginx and not PHP who is doing the gzip on the reply, I thought it would also work out of the box for Lua. What am I missing ?

Thanks for any advice,

Amnon

Yes, it should work out of the box. It's the standard ngx_gzip module
that does the gzip compression for you, no matter you're using PHP or
Lua.

Please provide a minimal but complete configuration sample that can
reproduce the issue and I'd like to have a look for you.

Thank you very much for the reply. I'll try and create a self contained example that illustrates the problem, but I'm happy knowing that it is supposed to work out of the box and what I'm experiencing is probably a configuration issue :)
