Redirect Field for Posts and Pages
Adds a "Redirect to" box to the post and page editor; when filled in, visitors who open that post are sent to the address you entered, on your site or elsewhere.
Snippet Library
Redirects snippets for WordPress
Snippets that send visitors where they should go: redirect after login or logout, from attachment pages, old URLs and empty searches, or to a maintenance page. Quick fixes when you only need a few redirects, not a redirection plugin.
