Redirection is a plugin to manage 301 redirections on your WordPress blog, and has just been updated to version 2.1.27. As well as 301 redirection, this plugin keeps track of all your 404 errors and generally tidy up any loose ends your site may have. This is also useful if you are migrating pages from an old website, or are changing the directory of your WordPress installation.

Some of the new features include;

• 404 error monitoring – capturing a log of 404 errors
• Custom ‘pass-through’ redirections allowing you to pass a URL through to another page, file, or website.
• Full logs for all redirected URLs
• All URLs can be redirected, not just ones that don’t exist
• Redirection methods – redirect based upon login status, redirect to random pages, redirect based upon the referrer!

Existing features of the Redirection plugin include:

• Automatically add a 301 redirection when a post’s URL changes
• Manually add 301, 302, and 307 redirections for a WordPress post, or for any other file
• Full regular expression support
• Apache .htaccess is not required – works entirely inside WordPress
• Strip or add www to all your WordPress pages
• Redirect index.php, index.html, and index.htm access
• Redirection statistics telling you how many times a redirection has occurred, when it last happened, who tried to do it, and where they found your URL
• Fully localized
