note 84176 added to book.session

Here is something to watch out for when working with sessions. Let's say you have two pages, Page A and Template Z. If Page A sets session data and includes Template Z, the session data is not properly registered for the execution of Template Z due to how session data is written *after* a script has executed [1]. As a result, your second page will not have the right session data, so you are a bit in a pickle. I'm sure there are other work arounds, perhaps with cookies or flat files, but you cannot use session data in that fashion. The reason I have this setup is because I will have a number of Page A-Z's that will contain page specific content and one Template Z page that renders each page's specific content in the site layout. This way, the site content changing is independent of the style the site uses and the site style can change without modifying the actual content. It's a dynamically configurable site template design.
