how did you know it goes to default pool? if there are number of requests (e.g. object inside web page), only the one containing "test=64" in request will go to test-temp pool. 

[root@ve10:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.252:80
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when CLIENT_ACCEPTED {
   set default_pool [LB::server pool]
}
when HTTP_REQUEST {
   set host [HTTP::host]
   set uri [HTTP::uri]
   if { [HTTP::uri] ends_with "test=64" }{
      pool test-temp
   } elseif { [HTTP::uri] contains "test=64&" }{
      pool test-temp
   } else {
      pool $default_pool
   }
}
when HTTP_RESPONSE {
   log local0. "client [IP::client_addr]:[TCP::client_port] | host $host | uri $uri | pool [LB::server pool] | server [IP::server_addr]:[TCP::server_port] | status [HTTP::status]"
}
}
[root@ve10:Active] config  b pool test-temp list
pool test-temp {
   members 200.200.200.111:80 {}
}
