How can I set a maximum limit for gzip module?

Hi t.nishiyori,

Don’t worry, just like Ermilov said, when you enable the gzip module and
nginx gets a part of response body, gzip module will try to compress the
data, and if the buffers reach the limit, gzip module just send these
compressed data firstly(ngx_http_gzip_body_filter), when processing by
chunk module, they evolved a “chunk”. After some buffers is free, gzip will
continue the work.

Hi tokers,

Thanks for explanation about gzip-module.
So, there were no errors when upstream response size exceeds the
But I think a lot of large responses exceed the prepared buffers, some day.
Is there any possibility of such a problem?

Thank you.
