Using https monitor with Oracle Access Manager

As I figured, if I want to get the Node ip, I need to use and irule and use it in an external monitor.... I was trying my best to follow the advice listed at the beginning of this external monitor....

NOTE: Use external monitors only when a built-in monitor won't do the trick. This example is intended to demonstrate the use of cURL (which offers a large number of other useful options) to insert variable headers in an external monitor. However, if nothing in the request varies, and don't need those extra options, more basic HTTP monitors are much more efficiently configured using the built-in HTTP monitor template instead.
