CirrostratusHere is a pretty concise summary from Unruley:
http://devcentral.f5.com/Default.aspx?tabid=53&view=topic&postid=12911
The LB_SELECTED event is only fired when a load-balancing decision is made. And of course, persistence only plays a factor when the load-balancing decision is made.
As a side effect of OneConnect, load-balancing will occur on every request. However, without OneConnect, load-balancing only occurs when the pool changes. Any subsequent requests that happen to go to the same pool will stay connected to the last pool member.
So, you have two ways you can change this behavior: 1) Add OneConnect; 2) at the beginning of HTTP_REQUEST call LB::detach.
