Based on the original Random Redirect, this plugin enables efficient, easy random redirection to a post. Supports setting a category for all random redirects, shortcodes to generate URLs that can override the default category, and setting your own redirector URL. Designed to scale to handle high-traffic websites with thousands of posts by using a more efficient strategy than most other redirection plugins employ.
