This release of the Redirect URL to Post plugin adds optional caching. The benefit of caching is increased speed and reduced burden on the database engine, particularly when using complicated query parameters or “random” on a huge number of posts.
1. In the URL
Add the parameter “&cache=600” to the URL. The number is the cache lifetime in seconds.
2. In wp-config.php
define('CHATTY_MANGO_RUTP_CACHE', 600 );
If you have debugging enabled, you will also notice some useful messages in the logs.
