Irule help 302 + maintain URI

I'm thinking something like the following snippet. I'm a total newb and haven't found any documentation yet. This would be where 10.1.1.[1-3] are pool members. being monitored. I'll test this out in the morning when I have some access, however I suspect this is close-ish. Is there anyway around editing the IRules anytime I want to add capacity? Is this even close to right?

 

 

Thanks again,

 

Justin
