Creating Search Engine Friendly URLs

[quote author="mattpointblank" date="1250873388"]In my URLs, I just append the ID after the slug, eg:

site.com/article/category/slug/123

Then if I ever need to rewrite my links (say we rename an article, or category) the link will still work:

site.com/article/news/obama-wins-election/123
is the same as
site.com/article/latestnews/new-president-elected/123

A bit more future proof I guess by linking articles to something that will definitely not change.[/quote]

And if user go to url:
site.com/article/news/obama-wins-election/

you should return 404 page
