Directive Reference

This appendix lists the configuration directives used throughout the book.

There are also some directives that did not appear in the book, but are listed
here for completeness. The entries have been expanded to show under which

context each directive may be used. If a directive has a default value, it has
been listed as well. These directives are current as of NGINX Version 1.3.9.

The most up-to-date list can be found at http://nginx.org/en/docs/

dirindex.html.
