http_only iRule no longer needed?

  We have recently upgraded from a pair of 6400's running 10.2.0 to a pair of 5000s' running 11.4.0 running LTM and ASM.  I had thought that at some point in between there that the http_only cookie issue was resolved either in LTM or ASM and that we no longer have to use this irule to fix the issue.  Can someone confirm this for me and, if so, shoot me the steps on doing so.

Thanks in advance,

    when HTTP_RESPONSE {
foreach cookie [HTTP::cookie names]
{
set value [HTTP::cookie value $cookie];
if { "" != $value }
{
set testvalue [string tolower $value]
set valuelen [string length $value]
log local0. "Cookie found: $cookie = $value";
switch -glob $testvalue {
"*;secure*" -
"*; secure*" { }
default { set value "$value; Secure"; }
}
switch -glob $testvalue {
"*;httponly*" -
"*; httponly*" { }
default { set value "$value; HttpOnly"; }
}
if { [string length $value] > $valuelen} {
log local0. "Replacing cookie $cookie with $value"
HTTP::cookie value $cookie "${value}"
}
}
}
}
