First of all, Redirection is an outstanding plugin that is enormously helpful! Thank you to the author for keeping it up to date.
I've noticed an issue where when using W3 Total Cache, if you change a post's permalink, and Redirection creates a redirect to the new permalink, users are not able to follow the redirect due to the old page (and URL) still being cached.
If we flush the entire page cache, the issue is fixed, but that's unfortunately counter productive. Is there any way in a future release of Redirection to have the plugin trigger a cache flush in W3TC?
