HeatMap for to identify hotspots on a cached service

Idea created by sjacksonesriaustralia-com-au-esridist Employee on Apr 22, 2010
    I would like to get an idea on which areas of my cache are getting hit the most.
    I would like to visualise these results using a heat map overlaid onto the same cached map. I was thinking of utilising something like the HeatMapsAPI and one of the APIs provided by ESRI (Javascript API should be sufficient).

    I know the cached maps might be slightly changing at v10 of ArcGIS Server, but im trying to think of the best way of determining which tiles get requested the most without putting a significant load on either ArcGIS Server or the web server (IIS).

    I was originally thinking looking at the actual cache directory under the arcgiscache folder, and perhaps hooking into the Date Accessed attribute (but have little idea on how to actually implement this).
