[Zope] How to get REST friendly urls from sql database

Hi. Normally a url to an article in our CMS system would look roughly like this: http://www.dom.tld/aritcles/25245 Where 25245 would be an object of some metatype, say 'article'. Now what if I wanted to get the data for that page from an sql server instead, I would expect to end up with a url like this: http://www.dom.tld/aritcles/index_html?id=25245 Now, having recently read the Roy Fielding paper, and expecting to do some caching, I would much prefer to have it the first way, even when I have to get the data out of a DB. Anybody have any ideas on how this might be done? Regards Gaute Amundsen
