Currently, when a tag page is loaded, the master theme checks if a "redirect page" is defined. If there is one, it fetches it's content for display instead of auto generating a tag page.

I'd like to have the ability to change this behavior in child themes/plugins to actually redirect to the URL of the redirect page instead of generating the output right away.

A possible solution would be to add an action hook before the output is generated.
