Cookie Persistence (iRule) Reset Timeout

So normally the cookie is inserted in only 1 response - you need the cookie inserted in every response so that it always expires in 60min. Let me know if this works;-

when HTTP_REQUEST {
    switch -glob [string tolower [HTTP::uri]] {
        “/example*”
        {
            pool VIPNAME1-POOLNAME
        }
        “/sample*”
        {
            pool pool VIPNAME-POOLNAME 
        }
    }
    persist cookie insert cookie "0d 00:60:00"
    set cname "BIGipServer[LB::server pool]"

    if {[HTTP::cookie exists "BIGipServer[LB::server pool]"} {
         Save the current cookie value
        set cvalue [HTTP::cookie $cname]
    } 
}

when HTTP_RESPONSE {
   if {![HTTP::cookie exists $cname]} {
         If there is no cookie in this response already,  insert one
        HTTP::header insert Set-Cookie "$cname=$cvalue; Path=/; Max-Age=3600; HttpOnly
   }
}
