Clarification on GTM Resolver cache

The Global Traffic Manager (a.k.a. GTM) and now referred to as DNS, is one of the cutting-edge modules offered on F5 Networks® BIG-IP® platform. “Global” is the right word for this module because it has the ability to make name resolution load balancing decisions for systems located anywhere in the world, not just the US. You can think of the GTM as an intelligent DNS that is security-minded. In other words its logic can make informed decisions on correlating a hostname to an IP address while keeping security in check.
