/**
* A Host is a Container that represents a virtual host in the
* Catalina servlet engine. It is useful in the following types of scenarios:
*
* - You wish to use Interceptors that see every single request processed
* by this particular virtual host.
*
- You wish to run Catalina in with a standalone HTTP connector, but still
* want support for multiple virtual hosts.
*
* In general, you would not use a Host when deploying Catalina connected
* to a web server (such as Apache), because the Connector will have
* utilized the web server's facilities to determine which Context (or
* perhaps even which Wrapper) should be utilized to process this request.
*
* The parent Container attached to a Host is generally an Engine, but may
* be some other implementation, or may be omitted if it is not necessary.
*
* The child containers attached to a Host are generally implementations
* of Context (representing an individual servlet context).
