>Everytime a page is processed, it is either a postback or a link to a new page. In both approaches, what I do is to pass a LXMessage in the query string, which contains a message to show. When the incoming hits is processed, if such a field is found in the query string, it will make it appear as an alert message, but only processed at the end of the page so everything has been loaded and thus you can see the message on top of the HTML display.

I think I start to understand. Let me see, if we use something similar to this approach already.
