      extended by org.apache.turbine.pipeline.DetermineTargetValve
All Implemented Interfaces:
Valve

public class DetermineTargetValve
extends AbstractValve

This valve is responsible for setting the 'target' property of the RunData. If it is not already set it attempts to get the target from the request parameter 'template'. If the parameter is not set, we use the homepage specified by the configuration property Turbine.TEMPLATE_HOMEPAGE. FIXME: The request parameter which determines the template should be configurable.
