iRules Heat Map - US Only

Code is community submitted, community supported, and recognized as ‘Use At Your Own Risk’.

Short Description

This iRule is an update to the original by Colin Walker. It takes source IPs and does a geolocation lookup on them and if within a US State, adds that as a counter against that state in the session table memory. A request to /heatmap on the applicable virtual server will display a US map with request counts from each state utilizing Google's GeoCharts.
