Hi,

You can try this irule 

when RULE_INIT {
    set static::local_dc "DtCnt1"
}

when HTTP_REQUEST {
    set setDCcookie 0
    if { [HTTP::cookie "DtCntPrstc"] ne $static::local_dc} {
        set setDCcookie 1
    }
}
when HTTP_RESPONSE {  
    if { $setDCcookie} {
        HTTP::cookie remove "DtCntPrstc"
        HTTP::cookie insert name DtCntPrstc value $static::local_dc
    }
}
