/**
 * A <b>Context</b> is a Container that represents a servlet context, and therefore an individual web application, in
 * the Catalina servlet engine. It is therefore useful in almost every deployment of Catalina (even if a Connector
 * attached to a web server such as Apache uses the web server's facilities to identify the appropriate Wrapper to
 * handle this request). It also provides a convenient mechanism to use Interceptors that see every request processed by
 * this particular web application.
 * <p>
 * The parent Container attached to a Context is generally a Host, but may be some other implementation, or may be
 * omitted if it is not necessary.
 * <p>
 * The child containers attached to a Context are generally implementations of Wrapper (representing individual servlet
 * definitions).
