Webcenter Cookie persistence

Hello,

I have some problems when implementing cookie persistence for an Oracle WebCenter pool . The problem is that when i add persistence using an irule, the value is not mantained and the persistence fails.

I have writed this irule to troubleshoot the problem. Please, any clue if is possible to enhance the solution? Or i have any mistake on the writed fields.

when HTTP_REQUEST priority 300 {

if { [HTTP::cookie "F5test"] ne "" } { 

    pool "p_evo_wl" 

    persist uie [HTTP::cookie "F5test"]

    if {[HTTP::cookie "F5test"] starts_with "f5id_"}{

         HTTP::cookie remove "F5test"

    }


} else {

    pool "p_evo_wl"

}  

}

when HTTP_RESPONSE {

if { [HTTP::cookie "F5test"] eq "" }{

   set rndumb "f5id_[expr { int(100000000 * rand()) }]" 


   HTTP::cookie insert name "F5test" value $rndumb"

   persist add uie $rndumb 14400 


} else {

   persist add uie [HTTP::cookie "F5test"]

}

}

Many thanks in advance!
