I'm refactoring the code used to getfeatureinfo from geoserver running on port 8080 at http://www.edpp.cz/zul_mapa-povodnoveho-planu-mesta/. The old version uses OpenLayers.loadURL and successfully requests the response from the server. The code is like:

map.events.register('click', map, function (e) {            
        var params = {
                REQUEST: "GetFeatureInfo",
                EXCEPTIONS: "application/vnd.ogc.se_xml",
                BBOX: map.getExtent().toBBOX(),
                SERVICE: "WMS",
                VERSION: "1.1.1",
                X: e.xy.x,
                Y: e.xy.y,
                INFO_FORMAT: 'text/html',
                QUERY_LAYERS: layers_on,
                FEATURE_COUNT: 1,
                Layers: layers_on,
                Styles: '',
                WIDTH: map.size.w,
                HEIGHT: map.size.h,
                format: format,
                srs: map.layers[0].params.SRS};

                OpenLayers.loadURL("http://localhost:8080/geoserver/wms", params, this, setHTML, setHTML);
                OpenLayers.loadURL("http://www.edpp.cz/mapinfo/geoserver/wms", params, this, setHTML, setHTML);


With the new code I try something like this:

popup = new OpenLayers.Control.WMSGetFeatureInfo({
            url: offline ? 'http://localhost:8080/geoserver/wms' : 'http://www.edpp.cz/mapinfo/geoserver/wms',
            layers: unbaseLayers,
            layerUrls: offline ? ['http://localhost:8080/geoserver/wms'] : ['http://www.edpp.cz/mapinfo/geoserver/wms'],
            title: 'Identify features by clicking',
            queryVisible: true,
            maxFeatures: 1,
            eventListeners: {
                getfeatureinfo: function(event) {
                    if (console) {
                    if (event.text.length > 1088) { // nezobrazí prázdné bubliny
                        map.addPopup(new OpenLayers.Popup.FramedCloud(
                nogetfeatureinfo: function(event) {
                    if (console) {

If I look into Firebug network log, I see that the clicking the map doesn't send any request to the geoserver (it runs fine on localhost though). Is this just a proxy related problem? I've already read about need to set up a proxy when running geoserver on the different port than a website. But it's really puzzling me there is no request being sent. Might it be a typo? I can't see any.

What if I am not able to set up a proxy, do I have any other option?

PS: All I get as a result is object of nogetfeatureinfo type.

The problem is the cross-domain request. The problem is not related on which port Geoserver is listening, the problem is that you can't do an AJAX request (getFeatureInfo in your case) on different domains.
