Welcome to the Q&A Forum

It does make sense Stephen, but this bit bothers me: The URL mappings must be used to redirect any link to a deleted page to an existent page. If I am reading that correctly then are they saying that 404's can't exist, just 302's? You don't always want to direct someone to a page, especially if it isn't applicable. In many cases, a 404 would be the right thing to do if a page is just being removed. Of course, if there is somewhere to redirect someone to, then you would do so with a 301 (permanent redirect) rather than a 302 (temporary redirect). I don't really understand their system, so might be missing something in translation. -Andy
