Class CssAcceptingHeaderResponseFilter

java.lang.Object
  org.apache.wicket.resource.filtering.AbstractHeaderResponseFilter
      org.apache.wicket.resource.filtering.CssAcceptingHeaderResponseFilter

All Implemented Interfaces:

HeaderResponseContainerFilteringHeaderResponse.IHeaderResponseFilter

public class CssAcceptingHeaderResponseFilter
extends AbstractHeaderResponseFilter

This filter accepts anything that appears to be CSS. All CSS that is not a resource reference ( AbstractHeaderResponseFilter.acceptOtherCss()) is accepted. All JS that is not a resource reference ( acceptOtherJavascript()) is not accepted. The references are accepted if they appear to be CSS. If the reference passed in is an instance of AbstractResourceDependentResourceReference, we use the AbstractResourceDependentResourceReference.ResourceType from it to determine if it is CSS. Otherwise, we see if the ResourceReference.name property ends with ".css".
