Summary

We explored the rewrite module of NGINX in this appendix. There are only a few directives associated with the module, but these can be used to create some complex configurations. Taking the process of creating new rewrite rules step by step has hopefully demonstrated how rewrite rules can be made easily. An understanding of regular expressions, how to read and construct them, is needed before creating the rewrite rules of any complexity. We rounded this appendix off by examining how to translate the Apache-style rewrite rules into a configuration that NGINX can parse. In doing so, we discovered that quite a few Apache rewrite rule scenarios can be solved differently in NGINX.
