session

Purpose

The session object is an instance of the Servlet API's HttpSession class

Examples

class UserController {
	def logout = {
		log.info "User agent: " + request.getHeader("User-Agent")
		session.invalidate()
		redirect(action:"login")
	}
	def login = {
	}
}

Description

The HttpSession class is useful for associated session data with a client.

Session attributes which are normally accessible via the getAttribute can also be indexed into using the array index operator or de-reference operator:

def user = session["user"]
session["user"] = "John"
asset "John" == session.user
