How to set HTTPOnly in cookie when HTTP::response & make the session persist on that cookie

I'm able to add secure flag with following simple Irule,

when HTTP_RESPONSE { set myValues [HTTP::cookie names] foreach mycookies $myValues { HTTP::cookie secure $mycookies enable } }

However, if I try to add httponly flag in the same irule it doesn't works.

when HTTP_RESPONSE { set myValues [HTTP::cookie names] foreach mycookies $myValues { HTTP::cookie secure $mycookies enable HTTP::cookie httponly $mycookies enable } }

I tried adding version 1 option also, no luck. Any quick help will be appreciated.
