Thanks for the great response. For me at least if the backend web servers are going to be using the same set apache ips I would have to create new pools containing the same set of ips, a seperate monitor, than add the pool to the irule that I pasted.

    True. To be thorough, you'd want to have separate pools with distinct monitors per application. If your requirements were more generic (i.e. you only care if the web server is up. you're not focused on specific web sites), you could have a single poo with a basic monitor checking just the root web site on the servers. If you need more specific checking (e.g. check that a login page comes up), you would need to have the different ones. The other option is to assign multiple monitors to a single pool, but the problem there comes because the monitors would be logically ANDed rather that ORed (so they both have to be up to be valid)
