I had same problem/question and trying with the configuration like this:

> cache_host P3 sibling <tcp-port> <udp-port>

The result is:
1.Almost work good :-)
2.Sometime P3 gets request even if P1/P2 are alive
3.POST method (maybe) always be sent to P3

I'd like to use P3 as real last-resort...
Can I use the weight option for this ?
