IRULES HELP

You don't need an irule to do this anymore you can do it with a traffic profile. Just create two pools using the ports specified in your table and configure a policy to route based on URI:

However if you want to use iRules, create two datagroups with the relevant URIs and use something like this:

when HTTP_REQUEST {
    if {[class match [HTTP::uri] starts with "pool-80-dg"] {
        pool pool-80
    } 
    if {[class match [HTTP::uri] starts with "pool-8080-dg"] 
        pool pool-8080    
    }
}
