I think this is just what I wanted. We are in the process of moving from 4.5.x to 9.x.y and have more than 50 rules per LB, they are all tweaked a little for each VIP. I would like to generalize to about 5 - 10 rules, to do this I need variable data per VIP.
Also to do this I could use an "init rule" to load the data or have the rule sense the data hadn't been loaded and load it at that time. If the rule senses the data is to be loaded it adds overhead.
if { [info exists ::slice_list] } {
if {$::slice_list(0) != "loaded" } {
Is there another / better way of doing this?
