Puppet, from Puppet Labs

It is a configuration management tool that helps system administrators automate the provisioning, configuration, and management of a server infrastructure.

Chef

It is a systems and cloud infrastructure automation framework that makes it easy to deploy servers and applications to any physical, virtual, or cloud location, no matter the size of the infrastructure. Each organization is comprised of one (or more) workstations, a single server, and every node that will be configured and maintained by the chef-client. Cookbooks (and recipes) are used to tell the chef-client how each node in your organization should be configured. The chef-client (which is installed on every node) does the actual configuration.

When a request comes to location \test, it will be processed by different phrases in sequence. There are 3 main phrases highlighted here out of totally 11 phrases. 1, rewrite 2, access 3, content

Every directive has its own phrase handler to be executed. For example set directive is executed in rewrite phrase, but echo is only executed in content phrase.

For rewrite and access phrases, directives from multiple modules can be executed, but in phrase content only one module is allowed to execute. For example，echo and echo_by_lua are conflicted if used together.
