Creates a handle for future use by ILX::call and ILX::notify. This handle is a reference to a running ILX plugin extension. The lifetime of this variable affects the behavior of the ILX target if controlled by BIG-IP. Instances of the plugin extension will be held in draining mode as long as there are open references to the ILX handle in any event.
Note: Whereas the ILX commands were introduced in 12.0, they were not available until 12.1 without an EA license.


Deprecated in BIG-IP Next v20.0.1
