Dear Carlo,
Thank you for the quick response...The following is the code what I am
using with openlayers+geoserver.
----------------------------------------------------------------------------------------------------------------------------------------------------
var map;
var mapUrl="http://localhost:8080/geoserver/wms";;
var SRID="EPSG:4326";
var controls={
'pzb': new OpenLayers.Control.PanZoomBar(),
'zoomOut':new OpenLayers.Control.ZoomBox({out:true}),
'zoomIn':new OpenLayers.Control.ZoomBox({out:false}),
'zoomToMaxExtent':new
OpenLayers.Control.ZoomToMaxExtent({type:OpenLayers.Control.TYPE_BUTTON}),
'dragPan':new OpenLayers.Control.Navigation(),
'nav': new OpenLayers.Control.NavigationHistory(),
'ls' : new OpenLayers.Control.LayerSwitcher(),
'overview':new OpenLayers.Control.OverviewMap(),
'mp': new OpenLayers.Control.MousePosition(),
'scale':new OpenLayers.Control.ScaleLine(),
'resolution': new OpenLayers.Control.Scale()
};
function init(){
var bounds = new OpenLayers.Bounds(81.511334, 24.823617, 82.354004,
25.751459);
var mapOptions = {
controls:[],
maxExtent: bounds,
numZoomLevels: 18,
maxResolution:'auto',
units: 'degrees'
};
map = new OpenLayers.Map('map_area', mapOptions );
var wms=new OpenLayers.Layer.WMS(
"India", mapUrl, {
srs: SRID,
LAYERS: 'Sample_layer',
STYLES: '',
transparent:true,
format: 'image/png',
tiled: true,
tilesOrigin : map.maxExtent.left + ',' + map.maxExtent.bottom
},
{
buffer: 0,
displayOutsideMaxExtent: true,
visibility: true,
isBaseLayer: true
}
);
map.addLayer(wms);
addOverlays();
for(var key in controls) {
map.addControl(controls[key]);
}
map.zoomToMaxExtent();
}
function addOverlays(){
var overlays = [
new OpenLayers.Layer.WMS(
"Overlay 1", mapUrl,
{
srs: SRID,
LAYERS: 'Overlay1',
transparent: true
},{
singleTile: true,
ratio: 1,
displayOutsideMaxExtent: true,
visibility: true,
isBaseLayer: false
}
),new OpenLayers.Layer.WMS(
"Overlay 2", mapUrl,
{
srs: SRID,
LAYERS: 'Overlay2',
transparent: true
},{
singleTile: true,
ratio: 1,
displayOutsideMaxExtent: true,
visibility: true,
isBaseLayer: false
}
),new OpenLayers.Layer.WMS(
"Overlay 3", mapUrl,
{
srs: SRID,
LAYERS: 'Overlay3',
transparent: true
},{
singleTile: true,
ratio: 1,
displayOutsideMaxExtent: true,
visibility: true,
isBaseLayer: false
}
),
.................
.............
.........
new OpenLayers.Layer.WMS(
"Overlay 100", mapUrl,
{
srs: SRID,
LAYERS: 'Overlay100',
transparent: true
},{
singleTile: true,
ratio: 1,
displayOutsideMaxExtent: true,
visibility: true,
isBaseLayer: false
}
)
];
map.addLayers(overlays);
}

I am using "sample map" as the base layer and 100 overlays(single tile).
Total no. of request is around 125 to geoserver on zoom/pan for one time.
This map will be used by n number of users.
*These are my problems....*
1. Geoserver is not responding properly
2. Responses is time consuming
*My queries.....*
1. How to control the above mentioned requests...?
2. Right now I am accessing GeoWebCache from this URL
*"../geoserver/gwc/service/wms".
*How to access cached tiles directly...?
3. How to configure Geoserver for production environment. I had a glance in
documentation of geoserver about configuring. Is that enough or some more
modification is needed ?
