How can I force WordPress to redirect to canonical permalinks?

Question

In WordPress 3.1 a post can be reached a number of ways, for example each one of these takes you to the same post (where /id is the base)

http://myblog.com/id/1008
http://myblog.com/id/1008/my-slug
http://myblog.com/my-slug

How can I tell WordPress to redirect all of these variations to

http://myblog.com/id/1008/my-slug

?

Answer 1

WordPress should do this automatically. Whatever permalink format you have set in Settings > Permalinks should be the URL visitors end up at when they come to a different URL that indicates the same content.

Answer 2

I use a plugin called Redirection (http://urbangiraffe.com/plugins/redirection/) that allows me to set up rules for url redirection. This might suit your needs if you can't get WordPress to do what you want.

wordpress does it automatically there is no need to do any thing if you have a custom structure defined in the settings->permalinks it will automatically redirect all the incoming structures to your custom structure or the one you have chosen in the settings in wp back end
