-    * In a microservice environment, it can be difficult to know in advance the exact origin
-    * from which requests may be issued [1]. For example, the request may come from a web page served from
-    * any of the services, on any namespace or from other documentation sites. In general, only a set

-    * in order to send credentials and headers with requests to other origins.
-    *
-    * This route wrapper provides a simple way alleviate CORS' exact allowed-origin requirement by
-    * dynamically echoing the origin as an allowed origin if and only if its domain is whitelisted.
-    *
-    * Note that the simplicity of this implementation comes with two notable drawbacks:
-    *
-    *   - All OPTION requests are "hijacked" and will not be passed to the inner route of this wrapper.
-    *
-    *   - Allowed methods and headers can not be customized on a per-request basis. All standard
-    *   HTTP methods are allowed, and allowed headers are specified for all inner routes.
-    *
-    * This handler is not suited for cases where more fine-grained control of responses is required.
-    *
-    * [1] Assuming browsers communicate directly with the services and that requests aren't proxied through
-    * a common gateway.
-    *
-    * @param allowedSuffixes The set of domain suffixes (e.g. internal.example.org, example.org) of allowed
-    *                        origins.
