Resolver
|

The type for each resolver config is *map*, with two always required keys:
|
|
|
|
* :ref:`name <conf_resolver_common_name>`, which specify the name of the resolver.
|
|
* :ref:`type <conf_resolver_common_type>`, which specify the real type of the resolver, decides how to parse other keys.
|
|
|
|
There are many types of resolver, each with a section below.
