A new way in Wicket 6

The org.apache.wicket.protocol.https.HttpsMapper can now be subclassed. This means that by overriding the org.apache.wicket.protocol.https.HttpsMapper.getDesiredScheme method you can programmatically determine what scheme to use.
Add this to your Application.java:

public void init() {
    super.init();
    setRootRequestMapper(new HttpsMapper(getRootRequestMapper(), new HttpsConfig(80, 443)) {
        @Override
        protected Scheme getDesiredSchemeFor(Class<? extends IrequestablePAge> pageClass) {
            if (getConfigurationType()==RunTimeConfigurationType.DEVELOPMENT) {
                return Scheme.HTTP;
            else
                return super.getDesiredSchemeFor(pageClass);
        }
    }
