Dear Geoserver users,
I am not sure if this should be posted here or on the OpenLayers list, but I will try here first. I am building an app using Geoserver and OpenLayers, and is based heavily on one of the examples included with OpenLayers (specifically getfeatureinfo.html). This is the line of code that I am interested in.
map.events.register(‘click’, map, function (e) {
$(‘nodeList’).innerHTML = “Loading… please wait…”;
var url = wms.getFullRequestString({
REQUEST: “GetFeatureInfo”,
EXCEPTIONS: “application/vnd.ogc.se_xml”,
BBOX: wms.map.getExtent().toBBOX(),
X: e.xy.x,
Y: e.xy.y,
INFO_FORMAT: ‘text/html’,
QUERY_LAYERS: wms.params.LAYERS,
WIDTH: wms.map.size.w,
HEIGHT: wms.map.size.h});
OpenLayers.loadURL(url, ‘’, this, setHTML);
Event.stop (e);
So, the user clicks the map and some information is returned from the WMS server based on where they clicked.
Sometimes, I see this in the logs of geoserver…

Is this a problem with geoserver or openlayers? Any pointers would be appreciated.
