I-rule persistence

sorry i still do not understand what the problem is. you can control bigip behavior using irule. for example, i want to send traffic to different pool based on uri. anyway, i need x-forwarded-for header and cookie persistence on one pool only. the following is my configuration.

[root@ve10:Active] config  b virtual bar list
virtual bar {
   snat automap
   destination 172.28.19.79:80
   ip protocol 6
   rules myrule
   persist cookie
   profiles {
      http {}
      tcp {}
   }
}
[root@ve10:Active] config  b pool foo1 list
pool foo1 {
   members 200.200.200.101:80 {}
}
[root@ve10:Active] config  b pool foo2 list
pool foo2 {
   members 200.200.200.111:80 {}
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
   switch -glob [string tolower [HTTP::uri]] {
      "/foo1*" {
         HTTP::header insert X-Forwarded-For [IP::client_addr]
         persist cookie
         pool foo1
      }
      default {
         persist none
         pool foo2
      }
   }
}
}

 1st request to /foo1/something
 on client

[root@centos11 ~] curl -I http://172.28.19.79/foo1/something
