In http context, add

include /path/to/8g-firewall.conf;

In the relevant server context, add

include /path/to/8g.conf;

In the relevant <Directory> section, add

Include /path/to/8G-SetEnvIf

To enable logging, add $ng_reason to the relevant log_format directive.

For best performance, add to the main context

pcre_jit on;

and place the include directive before any if, rewrite or set within the same context.

The eponymous module, mod_setenvif, is required, as is mod_authz_core. This is more efficient than using mod_rewrite.

For best performance, httpd.conf should be used in preference to .htaccess.

If even nG-SetEnvIf fails to satisfy your passion for performance, read on.
