Here is the use case when you need to supply more than one source domain.
The example file: simple-multiple-sources.yml has these sections.
This is the example specification of a refract in this way. The dst in on
the left and always ends with a trailing / and never has a scheme specified
like http:// or https://. In this case the srcs are a list of domains
that will all redirect to this desintation the same.
This section shows what the refract looks like after it has been loaded and
normalized to the these data fields. If unspecified status will default to
301. Any tests specified will be added to the generated tests. The number
of tests generated is always the product of srcs x dsts.
This shows the nginx that will be generated for this refract.
This is the output of the validate step done against a localhost running container. Each test loaded will be used in this step. The destination and status will be compared against the expected destination and status.
