Full list of iRules verbs

Take active_members for example. I couldn't find it in the LTM 9.0 PDF nor the HTML online. Also, searching for that string in the devcentral search box returns nothing even though it's in the forum search (googling for active_members f5 turns up nothing at all incidentally).

 

 

This leads me to another question: how can I tell if a pool exists before transitioning the traffic to it inside an iRule?

 

 

I look at the first part of the path and match it up against a known list of backends. I don't like this as it requires duplication of names (the pool itself and the iRule).

 

 

Thanks,
