How To GetFeatureInfo From a GeoWebCached Layer in Geoserver

Question

I'm really really struggling with this. I have created a map using Geoserver and Openlayers. Things have been working out here and there, as I am new to all this so a lot has been just trial and error. I noticed my map started loading slower and slower so I have decided to use GeoWebCache to cache my layers. The problem is that now I cannot get the feature info to display in a pop-up as it once was when I was getting the layers straight from the server/wms. The part that even confuses me further is that when I provide the pop-up with the url 'http://localhost:8080/geoserver/gwc/service/wms' it actually attempts to send a request. However when I provide the right url from the server where the data actually is (http://localhost:8080/geoserver/wms), it's like if no request is being made. (I am seeing this in firebug). I've also created a geowebcache.xml files and have listed several of my layers as true, but no differences there either :( Any suggestions you can offer me will be greatly appreciated. I am truly very stuck.

Many thank yous,

Finally I have stumbled across here:

http://getsatisfaction.com/opengeo/topics/error_in_wmsgetfeatureinfo#reply_2612983

new OpenLayers.Control.WMSGetFeatureInfo({

    url: "http://localhost:8080/geoserver/wms", 

    layerUrls: ["http://localhost:8080/geoserver/gwc/service/wms"],

    title: 'Identify features by clicking',

    queryVisible: true

});

Turns out what I was missing was layerUrls: ["http://localhost:8080/geoserver/gwc/service/wms"]

This means: consider the layerUrls (i.e. your gwc urls), but issue requests to the url (i.e. your wms url).
