AdHocContextValvepublic 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. |
