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

Tried few more following combinations, had no luck.

a)

when HTTP_RESPONSE { Check if the response contains the persistence cookie

if {[HTTP::cookie test_Cookie] ne ""}{

 Set the httponly & secure flag on the persistence cookie if it is in the response

 HTTP::cookie httponly test_Cookie enable
 HTTP::cookie secure test_Cookie enable
}

}

b)

when HTTP_RESPONSE {

 Set the httponly & secure flag on the persistence cookie if it is in the response

 HTTP::cookie version test_Cookie 1
 HTTP::cookie httponly test_Cookie enable
 HTTP::cookie secure test_Cookie enable
}

}

Any ideas where am I heading wrong ?
