    The iRule and solution Kevin provided in that link looks to be exactly what you need. And yes, you can reference more than one URL in the data group to point to the same node.

I'm testing the solution and getting inconsistent results. Some URLs direct properly and others dont. I want customer1.com to be directed to node 10.10.15.1, customer2.com to be redirected to 10.15.15.1 and so on. each customer URL goes to its own node. The data group seems to work, but as I said, it's inconsistent. My data group looks like customer1.com := 10.10.15.1 80 customer2.com := 10.15.15.1 80 customer3.com := 10.15.16.1 80 My irule in place is when HTTP_REQUEST { if { [class match [string tolower [HTTP::host]] contains Shared_DataGroup] } { set my_node [split [class match -value [string tolower [HTTP::host]] contains Shared_DataGroup]] node [lindex $my_node 0] [lindex $my_node 1] } } suggestions are welcome.
