    public class ContextHandlerCollection

extends HandlerCollection

ContextHandlerCollection. This `HandlerCollection` is creates a `PathMap` to it's contained handlers based on the context path and virtual hosts of any contained `ContextHandler`s. The contexts do not need to be directly contained, only children of the contained handlers. Multiple contexts may have the same context path and they are called in order until one handles the request.
