At the moment, the expiry of eVars is very limited
Examples of why this is bad
s.eVar1 = "~empty~"
Which would reset the eVar at that point. It could be done in the s_code or in the DOM
Ideally I'd like to see Adobe allow us to select multiple expiry options for each in the admin console.
Yes we need a way to expire an eVar by more than one custom event. I want to use this for listvars so that I can measure impression/click events in a single listvar.
