client connection persistence using an irule

Lee

I tried with client -ip it dint work as when i look into the packet header i see iv-remote-addess or x-forwaded for info.

when HTTP_REQUEST {

      if {[HTTP::header exists iv-remote-address]} {

          persist uie [HTTP::header value iv-remote-address]

  }

}

when HTTP_RESPONSE {

if {[HTTP::header exists iv-remote-address]} {

          persist add uie [HTTP::header value iv-remote-address]

      }

  }

when i create a uie persistence profile , can i use the parent source IP or it had to be something different and also in the above irule if the header does not have the client ip info i need the packet to be dropped .Can i create a seperate irule to validate the header and apply the persistence irule to the IUE persistence profile and the above iRule to the VIP itself
