I am developing a real estate search engine using primarily Dreamweaver for the search, results, and details page functionality. The site is working very slick and its time to add an "Add to Favorites / View Favorites" feature. When a consumer searches for properties, we want to give them the ability to add property detail pages to their list of favorites. When they leave the site and come back, we also would like them to be able to log in and view the list of favorites. I know this involves sessions. Where do I begin?
