Message.Reloaded Property
Gets whether the message was created on a previous page of the web site. Script: http://www.wlmessenger.net/api/3.7/loader.js
Feature: Messenger.Core
Namespace: Microsoft.Live.Messenger
The Reloaded property returns whether the message existed before the current page was loaded. Since a user can remain signed in as he or she navigates a particular web site, this property enables an application to distinguish between a message that was sent or received on a previous page and a message that was sent or received on the current page.
