I’m using W3 Total Cache 0.9.1.3 on WordPress MU 2.7, and if I enable enhanced disk cache, URLs like http://richardxthripp.thripp.com/tweet-this don’t forward to http://richardxthripp.thripp.com/tweet-this/ (I use trailing slashes in my permalinks). HTTP 200 is returned instead of HTTP 301. However, with the standard disk cache the redirects work fine.
Is this an Apache issue, a W3 Total issue, or a WP issue? Upgrading from WPMU 2.7 is not an option, so please don’t suggest it.
