How do you build an iRule to re-direct a VIP to a server based on URL?

What is the difference between the to I rules you guys posted?

The node command sends to a specific node, regardless of pool membership, while the pool command, specifically pool [pool name] member [IP] [port] sends traffic to a specific pool member, which must exist in the pool. In my opinion, using the node command is really no better or worse than using the pool member command. They're both targeting a specific service regardless of any load balancing or health status. You didn't mention a pool configuration, so I went with the node option.
