Custom Routing

I have CISCO 1811 and having following network setup –

—–>>10.0.0.1(fa01)[CISCO1811]——>>FA03
——->>FA04

The traffic coming on fa01 10.0.0.1 is traffic form ISP to Internet having destination address to websites like yahoo google etc. My requirement is how can i setup routing so that traffic for yahoo goes to fa03 and traffic for google go to fa04 and so on for other websites too on different out ports. I have the IPs for yahoo and google through nslookup command.

please suggest how to do this
