I would like to build a navigation bar at the top of my pages that consist of home and the last four pages they came from. Can this be done?
Not literally the way you have stated it. The pages "they" came from are known to "their" browser, but you can't know what they were unless you put some monitoring demon on "their" machine, or unless you run some javascript in a page to look at the browser history (I'm not sure that security protections would allow that across sites). In any event, this would constitute spying on a person's browsing behavior, which is a very unfriendly thing to do IMHO. Perhaps you mean something a little different. Perhaps you mean the last pages ***from within your site***. You could do that with cookies, or by using forms. Each hyperlink could actually send you a form with hidden variables showing the last pages. Each page would have to be built dynamically each time so that you could insert the updated values in the hidden fields. Or, you could save the information in session variables. Cheers, Tom P
