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!

Javier

    I suspect this;

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

    should be;

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

    The problem is that when i add persistence using an irule, the value is not mantained and the persistence fails.

     

    i do see client sending cookie back to virtual server in the next request. persistence record seems to be created properly.

     

    by the way, why do you have to change cookie value on every response?
