I am using WP Super Cache on a multisite 3.0.1 installation. For some reason, many of the Super Cached RSS feed files are not expiring properly.
For example, a custom feed URL such as http://example.com/feed/?taxonomy=test&term=test-term
That feed gets cached by WP Super Cache on the first request, but it does not expire as new posts are published, and it does not even expire after my time limit setting of 230 seconds.
Is there something in my WP Super Cache configuration that may be causing this, or could this be a bug with WP Super Cache?
Thanks for your help,
