Headers-More

The headers-more module allows you to add, set, or remove any outgoing or incoming headers.

Loading the Module

To use the module, it must be loaded in the context of main{}:

load_module modules/ngx_http_headers_more_filter_module.so;

In the configuration example below, directives from the echo module are also used along with the module's own directives. Loading the echo module:

load_module modules/ngx_http_echo_module.so;
