Example ConfigurationDirectives      sliceEmbedded Variables
The  ngx_http_slice_module  module (1.9.8) is a filter that splits a request into subrequests, each returning a certain range of response. The filter provides more effective caching of big responses.
This module is not built by default, it should be enabled with the  --with-http_slice_module  configuration parameter.
Example Configuration
 

location / {
    slice             1m;
    proxy_cache       cache;
    proxy_cache_key   $uri$is_args$args$slice_range;
    proxy_set_header  Range $slice_range;
    proxy_cache_valid 200 206 1h;
    proxy_pass        http://localhost:8000;
}

In this example, the response is split into 1-megabyte cacheable slices.
Directives
Syntax: slice size ;
Default:

slice 0;

Context: http ,  server ,  location
Sets the  size  of the slice. The zero value disables splitting responses into slices. Note that a too low value may result in excessive memory usage and opening a large number of files.
In order for a subrequest to return the required range, the  $slice_range  variable should be passed to the proxied server as the  Range  request header field. If caching is enabled,  $slice_range  should be added to the cache key and caching of responses with 206 status code should be enabled.
Embedded Variables
The  ngx_http_slice_module  module supports the following embedded variables: $slice_range
the current slice range in HTTP byte range format, for example,  bytes=0-1048575 .
