Hi,
I have WMS overlays (source http://iridl.ldeo.columbia.edu) in my GIS
application (built on ExtJS, Mapfish, OpenLayers). It works, but the
overlays do not seem to show up any faster after the first load and the
Chrome inspector confirms that. So I talked to the guys at columbia.edu and
they say that they can se 'Pragma: no-cache' in my getMap requests.
My WMS layers are created like this:
new OpenLayers.Layer.WMS(
<name>,
<url>,
{
layers: <layers>,
transparent: true,
format: 'image/png'
},
{
isBaseLayer: false,
buffer: 0,
ratio: 1,
singleTile: true
}
)
How can I control the Pragma parameter? It is obviously not provided in the
base url.
Jan
