Hi,
I have the USA Zipcode shapes as features in an InMemoryFeatureLayer. I let the user select 1..n of these features by drawing a shape on the map (clientside). On the serverside, I then add all the zipcode features that intersects with the drawn shape to the highlight layer.
Looking at the get request in firebug, the map control requests _all_ the tiles for _all_ the dynamic layers. What I want to do is to request only those tiles that have changed to show the selected features.
Any help is greatly appreciated.
Thanks,
Chris
