Directing traffic to a specific pool member

That's pretty easy as well, actually, as long as you have the IP addresses of the members in question.

So if member 1 is 10.10.10.10, and member 5 is 10.10.10.14:

when HTTP_REQUEST {
  switch -glob [string tolower [HTTP::path]] {
    "/paymentResponse1.jsp" {
      pool resp_pool member 10.10.10.10 80
    }
    "/paymentResponse2.jsp" {
      pool resp_pool member 10.10.10.11 80
    }
    "/paymentResponse3.jsp" {
      pool resp_pool member 10.10.10.12 80
    }
    "/paymentResponse4.jsp" {
      pool resp_pool member 10.10.10.13 80
    }
    "/paymentResponse5.jsp" {
      pool resp_pool member 10.10.10.14 80
    }
  }
}

And if you have many more you could use a data group and the class command to simplify the long switch case.
