private Handler < Void > installAfterHandler ( final HttpServerRequest request , final Buffer buffer , final List < Listener > afterListener ) { Handler < Void > afterHandler = null ; return afterHandler ; }
this handler is called after the self request ( original request ) is performed successfully . the handler calls all listener ( after ) , so this requests happen after the original request is performed .
