AdHocContextValve

public class AdHocContextValve extends Object implements org.apache.catalina.Valve
Implementation of StandardContextValve which is added as the base valve to a web module's ad-hoc pipeline. A web module's ad-hoc pipeline is invoked for any of the web module's ad-hoc paths. The AdHocContextValve is responsible for invoking the ad-hoc servlet associated with the ad-hoc path.
