[Tilecache] Multiple URLs for layer

[Paul Spencer]

Ian,

you should use multiple urls in your javascript code to point to your  
tilecache instance when defining your layer, not in the tilecache  
configuration file.

In your tilecache configuration file, you provide the URL to the wms  
server which is drawing your tiles for you, it is just a single URL.

So, in javascript:

var layer = new OpenLayers.Layer.WMS(
     'MyTiledLayer',
     ['http://serv1.site.com/tilecache/tilecache.py',
      'http://serv2.site.com/tilecache/tilecache.py',
      'http://serv3.site.com/tilecache/tilecache.py',
      'http://serv4.site.com/tilecache/tilecache.py'],
     {layers:'layer'},
     {/* other options */}
);

Where the four urls all point to the same tilecache instance

And in tilecache.cfg

[layer]
type=WMS
url=wms.server.com
layers=mapname # these are the layers from the wms to draw
# and other options

Cheers

Paul
