Pool load balancing to one node

Hi NiHo,

the fallback SRC_IP persistence profile should be removed. It will most likely cause the ISAPI servers (i assume the ISAPI are forwarding the requests in a full proxy mode) to use SRC_IP persistence, if the first request does not already contain a valid persistence cookie. In the end a single ISAP Server (single IP) would always become balanced to a single pool member (same persistence record).

So just use "Round Robin" or "Least Connection" balancing (will be used for the first request) and just use a Cookie based persitence (will be used for subsequent requests from the same client).

Note: If cookie persistence alone is not stable enough, then you may want to implement UIE persistence based on a custom Cookie AND X-Forwarded-For header information passed by your ISAPI application (as fallback).

Cheers, Kai
