LB::reselect not working as expected

I'm got an LB_SELECTED that is checking if the choice made by the LB is acceptable, and doing an LB::reselect if not. I setup an artificial condition in my lab in which no choice is acceptable. Base...

Citizen,

Thanks for your help. I thought of doing that. I'd have to:

1) maintain a class with the same information that's already in the pool definition. If there were some way to find out the pool members from within the irule, then I would be nicer. But I could do this.

2) In order to "load" the class data with the current ratios, i'd have to make a pass through LB_SELECTED for each server in the pool. I guess the only way to reliably do this is via a "pool member " from the CLIENT_DATA event. i.e. pseudocode

CLIENT_DATA

foreach member in class

if member(capacity) uninitialized

pool

elsif member(capacity) > incoming client's weight

pool

endif

endfor

LB_SELECTED

if uninitialized capacity value for this member

member(capacity) = [LB::server ratio]

if member(capacity) < incoming client's weight
