The DynamicRedirect extension provides redirection to a dynamically determined page. In the current version, the target can be determined either by evaluating a piece of wikitext, or chosen from a category.

Usage

the user is redirected to a page chosen based on the values of the parameters:
 * is the primary mode selector, the currently supported values are:
 * – parse the expression given in  and use the resulting text as the page title to redirect to
 * – redirect to the first page in the category which title is in  (without the Category: prefix)
 * – redirect to the last page in the category which title is in  (without the Category: prefix)
