Second set of eyes, please

Hi Lucky,

As Matt suggested, if you're wanting to test on 10.1.x, LTM VE is a great option.

I think it would be more efficient to define the host to pool mapping in a datagroup rather than defining the mapping in an array that you declare for every request. You can use findclass to look up the host in the class:

String type datagroup which maps the host names to pool names:

class host_pool_map_class {
  "host1 pool1"
  "host_other some_pool"
}

iRule which references the datagroup:

when HTTP_REQUEST {

    Check if there is a host header value
   if {[HTTP::host] ne "" {

       Check if the requested Host is in the host_pool_map_class datagroup
      set my_pool [findclass [string tolower [HTTP::host]] $::host_pool_map_class " "]

       if { $my_pool ne "" } {
         pool $my_pool
      }
   }
}

Note, if you're on 9.4.4 or higher, you should remove the $:: prefix from the iRule's reference of the datagroup.
