Module ngx_http_gunzip_module

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.

location /storage/ {
    gunzip on;
    ...
}

gunzip off;

Enables or disables decompression of gzipped responses for clients that lack gzip support. If enabled, the following directives are also taken into account when determining if clients support gzip: gzip_http_version, gzip_proxied, and gzip_disable. See also the gzip_vary directive.

gunzip_buffers 32 4k|16 8k;

Sets the number and size of buffers used to decompress a response. By default, the buffer size is equal to one memory page. This is either 4K or 8K, depending on a platform.
