Clearcode

This plugin allows you to create simple redirect requests to another page on your site or elsewhere on the web.
Redirects format is similar to the one that Apache uses. The <code>From</code> field should be relative to your website root. The <code>To</code> field can be either a full URL to any page on the web, or relative to your website root. 
From: <code>/old-page/</code> To: <code>/new-page/</code> 
From: <code>/old-page/</code> To: <code>http://example.com/new-page/</code>
To use wildcards, put an asterisk <code>*</code> after the folder name you want to redirect. 
From: <code>/old-folder/*</code> To: <code>/redirect-everything-here/</code>
You can also use the asterisk <code>*</code> in the <code>To</code> field to replace whatever it matches in the <code>From</code> field. 
From: <code>/old-folder/*</code> To: <code>/some/other/folder/*</code> 
From: <code>/old-folder/*/content/</code> To: <code>/some/other/folder/*</code>
