 *  1. If the current call already has a connection that can satisfy the request it is used. Using

 *  2. If there is a connection in the pool that can satisfy the request it is used. Note that it is

That confirms that you are being able to serve static files from your app, and that you placed the static files for the docs in the correct place.

Now we can configure the app to use those static files for the docs.

Now, let's see how you could use that to return a custom response.

Let's say that you want to return an <a href="https://en.wikipedia.org/wiki/XML" class="external-link" target="_blank">XML</a> response.

You could put your XML content in a string, put that in a `Response`, and return it:

   * Internet users can register subdomains. An example of a public suffix that is not a registry
   * suffix is {@code blogspot.com}. Note that it is true that all public suffixes <i>have</i>
   * registry suffixes, since domain name registries collectively control all internet domain names.
