Module ngx_http_random_index_module

The ngx_http_random_index_module module processes requests ending with the slash character (‘/’) and picks a random file in a directory to serve as an index file. The module is processed before the ngx_http_index_module module.

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

    random_index on;
