Hello List
I use http://tile.openstreetmap.org/${z}/${x}/${y}.png to display the
map in my web application
I use a filter mechanism in the servlet, where an expiry header and
maximum age headers are added to the image requests, so that they will
be cached for a while on the client browser. These are just for common
images that the application use like tooltip.png and button.png and
such...These are called from the cache just fine
Now to do the same for osm tiles I added a proxy through which the tiles
are requested and then expiry headers are added to these tiles, Say
http://myapplciation.com/proxy?url=http://tile.openstreetmap.org/${z}/${x}/${y}.png.
This is the layer address in OpenLayers.Layer.OSM
An expiry header is added correctly to osm tiles. The problem is that
the imagename in the request is different than in the response, so if
I'm requesting |http://tile.openstreetmap.org/16/34687/21558.png I get
an image called 2736BB16d01.png in my cache. So that by the next call
this image won't be fetched from the cache and instead called again from
the server and so on.
Is there a way to force the browser to load the images from its cache if
available?
Thnx in advance
Moataz
