IP tables - ip forward to another ip

Hi all,

Now my need is:

This should forward each client to 1.11 and 1.12 as per each request.

I mean :
First request should go to            : http://192.168.1.10:8080/MySite
Second request should go to       : http://192.168.1.11:8081/MySite
Third request should go to           : http://192.168.1.12:9083/MySite

Fourth request should go to         : http://192.168.1.10:8080/MySite
Fifth request should go to            : http://192.168.1.11:8081/MySite ......etc

it will be rotating like this.

How this can make possible..??

Not with iptables.. but how about:
