iRule to rewrite cookie domain to toplevel domain

I have to domains, 1. xyz.abc.com 2. xyz.abbc.com Now when I am trying to change the domain of the cookie at the toplevel the below iRule isn't working. when HTTP_RESPONSE { set a ".abc.com" set...

Finally I was able to set the cookie domain to toplevel by using the following iRule. Cookies are set to toplevel domain now by using HTTP::host and comparing directly with the domain values I have. What do you think about the following iRule? Any flaws?

when HTTP_REQUEST {
    log local0. "Cookie names in received request: [HTTP::cookie names] from IP: [IP::local_addr]"
   set httphost [HTTP::host]
}

when HTTP_RESPONSE { 
    foreach mycookie [HTTP::cookie names] { 
     log local0. "Host : $httphost"
        if { $httphost ends_with ".abc.com" } { 
            HTTP::cookie domain $mycookie ".abc.com"
        } elseif { $httphost ends_with ".abbc.com" } { 
            HTTP::cookie domain $mycookie ".abbc.com"
        } else {
          log local0. "Not a single cookie domain matched :"
        }
    } 
}
