Usually when i want to create a diagram that displays the pages in a web application and the links that allow you to navigate from one page to another I use the UML statechart diagram. I don’t think statecharts where intended for this purpose but it works in communication with clients and other developers. Are you also using this or are you using something else?
I haven’t looked at the upcoming UML 2.0 yet, are there any new diagrams for this purpose?
