Assign specific uri to a server\node in pool

You can create pool for server1 and server2 and use all services under service port while adding node. Reference that pool in the iRule and it should work.

when HTTP_REQUEST {
set uri [string tolower [HTTP::uri]] 
if { $uri contains "server1" } {
pool pool1
} elseif { $uri contains "server2" } {
pool pool2
} else {
pool test1
 }
}
