Lazyweb request – I am trying to make sure WordPress is not caching RSS feeds, I tried these things but it did not work. WordPress devs, please get in touch if you have any ideas! I am trying to test a RSS Cloud plugin I developed.

@AndySylvester Could it be that some other service is caching the feed? Either another plugin or something at your host like a load balancer or CDN? Those are a few things I'd look into.
