Plugin for YOURLS v1.7 (earlier versions not tested). Adds a custom API action regenerate_url, which generates a new keyword for a URL that has already been shortened.

The API action regenerate_url accepts two parameters:

• old: the URL you want to regenerate. Accepts both keywords (abc) and shortened URL's (http://sho.rt/abc).
• new (optional): the new keyword for the shortened URL. If this parameter is not passed, a random keyword will be generated (according to the rules and plugins you currently use).

1. Copy this folder to /user/plugins.
2. Go to the Plugins Administration page (e.g. http://sho.rt/admin/plugins.php) and activate the plugin.
3. Have fun!

YOURLS' license, aka "Do whatever the hell you want with it".
