public class CookieContext
extends Object

A cookie management abstraction into a Mentawai context. Note that this class is smart enough to keep track of which cookies were added, which ones were removed and which ones did not suffer any modification and should not be sent again to the browser.

setAttribute

public void setAttribute(String name,
                         Object value)

Sets a cookie to send to the client in the response. Note that this method can take a Cookie as the value as well as a String.
