iRule for Pool member redirection

Question

Hi,
I have a requirement from my customer. Need some advice how to proceed with iRule with iApp.&nbsp;
Fqdn : abc.def.com (user would be accessing abc.def.com/ghi and abc.def.com/jkl)
VS_IP: 10.20.30.40
Servers in the pool : over 7013,7023
10.20.30.50:7013 and 10.20.30.60:7013 (should reach to the module abc.def.com/ghi)
10.20.30.50:7023 and 10.20.30.60:7023 (should reach to the module abc.def.com/jkl)&nbsp;
Here is my plan please correct me if I am wrong and share the iRule:
1. Will create a VIP with all pool member on iApp.
Fqdn : abc.def.com
VS_IP: 10.20.30.40
2. Will place iRule to reach to first pool member for /ghi else second pool member for /jkl&nbsp;
Can anyone help me with the iRule and suggest if this way I can achieve the target.&nbsp;
Thanks,
Nantu&nbsp;

What is with persistence profiles? Can you attach different persistence profiles, too? Or will be the default persistence profile attached to the different pools?

You can attach multiple persistence profiles to a virtual server (not a pool).  You can set primary and fallback persistence profiles, or multiple primary profiles with a one as the default.

Hey Nitass,
I have gone through both of the solution. I will try to apply Tomorrow on my LB. I am going to configure one iApp with default pool. Also will apply one iRule to the VS.
Like this: Will this work?
when HTTP_REQUEST {
    if { [HTTP::uri] starts_with "/foo" } {
      pool foo
    } else {
      pool bar
      }
  }

Or, Should I use the next one:
 when CLIENT_ACCEPTED {
     since no LB decision has been made for each brand new connection, 
    [LB::server pool] returns the name of the default pool configured on the virtual server
    set def_pool [LB::server pool]
  }
  when HTTP_REQUEST {
    if { [HTTP::uri] starts_with "/foo" } {
      pool foo
    } else {
      pool $def_pool
    }
  }
