KTCPVS has cookie-injection load balancing feature just as you described.
You can use something like the following
insmod ktcpvs.o
insmod ktcpvs_chttp.o
tcpvsadm -A -i http -s chttp
tcpvsadm -a -i http -r realserver1:80
tcpvsadm -a -i http -r realserver2:80
tcpvsadm -a -i http -r realserver3:80
Anyway, please test it yourself first, use it at your own risk. :)
