Show tiles within a specific extent

[roialgavish]

Hello,

I have a cached map server with a very large extent, I am building an app with the ArcGIS JavaScript api and I want to show only a specific tiles every time that the app Is loaded (as a result of the extent of another layer). I can't figure out how to do it.

I need something like the opposite of the setExclusionAreas() method.  

Any ideas?

setExclusionAreas is an array, so you can calculate 4 extents to exclude everything but your target area.
