Web Application Context Handler.

The WebAppContext handler is an extension of ContextHandler that coordinates the construction and configuration of nested handlers: ConstraintSecurityHandler, org.eclipse.jetty.ee10.servlet.SessionHandler and ServletHandler. The handlers are configured by pluggable configuration classes, with the default being WebXmlConfiguration and JettyWebXmlConfiguration.
