Hi Amar,
I'm hoping the primary question is enough for someone to answer this rather than investigate the set-up of this specific SLT instance. e.g. I haven't gone down the path of investigating too heavily how this works since this is obviously a feature.
That said, if no one who knows about this feature responds to this question, and I hear back from the HEC team that they haven't done anything to activate this; I'll start to do the heavy lifting and reverse engineer how this is happening (and post back on this discussion my findings).
BTW - If you have a specific transaction or web page to investigate the config for the SLT about where this feature might be referenced, feel free to let me know and I'll post back my results.
Cheers,
Matt
