LB commands documentation

I'm looking for documentation on the LB commands.

 

 

I'm trying to persist on a session id found in a response, and it needs to be qualified by which pool member issued it. I've seen references to LB:: commands in various iRule scraps, but I can't find any documentation on them.

 

 

What I need is to find some command that will return a "hostname" for the selected load-balance pool member. Something like "server1", "server2", etc. Then I could rewrite the response to add that qualifier, and rewrite subsequent requests to remove it.

 

 

I realize I could do this by modding the application, but I'd like to see if I can use the power of the F5 to avoid that. (I also I realize that I could get around the problem by assigning disjoint connection-id ranges to different members, but that seems to be only a short-term solution.)
