iRule to redirect users to a pool based on POST data

the irule looks okay to me.

have you run tcpdump? was there any suspicious there?

tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap host x.x.x.x or host y.y.y.y and port zzz

x.x.x.x is virtual server ip

y.y.y.y is pool member ip

zzz is port number

this is my testing.
