/**
* ContextHandler.
*
*
* This handler wraps a call to handle by setting the context and servlet path, plus setting the context classloader.
*
*
* If the context init parameter {@code org.eclipse.jetty.server.context.ManagedAttributes} is set to a comma separated list of names, then they are treated as
* context attribute names, which if set as attributes are passed to the servers Container so that they may be managed with JMX.
*
*
* The maximum size of a form that can be processed by this context is controlled by the system properties {@code org.eclipse.jetty.server.Request.maxFormKeys} and
* {@code org.eclipse.jetty.server.Request.maxFormContentSize}. These can also be configured with {@link #setMaxFormContentSize(int)} and {@link #setMaxFormKeys(int)}
*
*
* The executor is made available via a context attributed {@code org.eclipse.jetty.server.Executor}.
*
*
* By default, the context is created with the {@link AllowedResourceAliasChecker} which is configured to allow symlinks. If
* this alias checker is not required, then {@link #clearAliasChecks()} or {@link #setAliasChecks(List)} should be called.
*
* This handler can be invoked in 2 different ways:
*
* -
* If this is added directly as a {@link Handler} on the {@link Server} this will supply the {@link CoreContextHandler}
* associated with this {@link ContextHandler}. This will wrap the request to a {@link CoreContextRequest} and fall
* through to the {@code CoreToNestedHandler} which invokes the {@link HttpChannel} and this will eventually reach
* {@link ContextHandler#handle(String, Request, HttpServletRequest, HttpServletResponse)}.
*
* -
* If this is nested inside another {@link ContextHandler} and not added directly to the server then its
* {@link CoreContextHandler} will never be added to the server. However it will still be created and its
* {@link ScopedContext} will be used to enter scope.
*
*
