The {jakartaee}jakarta/servlet/http/HttpSession.html[HttpSession] class is useful for associated session data with a client.
Session attributes which are normally accessible from the {jakartaee}jakarta/servlet/http/HttpSession#getAttribute(java/lang/String).html[getAttribute] can also be indexed into using the array index operator or de-reference operator:
def user = session["user"]
session["user"] = "John"
assert "John" == session.user
