Standard cookies offer minimal relief but are very limiting in the amount of data they can store.
These files are XML files and and are more easily manipulated than standard cookies using the XML Document Object Model. In this article, we demonstrate a simple use of the XML persistance format to create a site favorite list. The site favorite list lets users add pages to a site-specific favorite list plus a simple mechanism for retrieving and viewing the list. To enable the XML persistance you need to apply the IE5 user data behavior to an element in your document. For favorites, we chose to apply the behavior to a custom element.
