Answer 1

Apparently there is some way to do this. Nginx has a gunzip module that gzip decompresses responses:

The ngx_http_gunzip_module module is a filter that decompresses responses with “Content-Encoding: gzip” for clients that do not support “gzip” encoding method. The module will be useful when it is desirable to store data compressed, to save space and reduce I/O costs.

This module is not built by default, it should be enabled with the --with-http_gunzip_module configuration parameter.

Source: http://nginx.org/en/docs/http/ngx_http_gunzip_module.html

Then you can use it like:

gunzip on;

Hope that works for you.
