I'm using an RSS feed to populate my homepage at
www.ucradiopodshow.com
I've noticed that at times, when I update the RSS file, it takes up to an hour for the homepage to reflect the changes. Is there a way to set the page up so that it will update immediately? Or at least check every few minutes to see if it needs to update?
What are you using to create and display your feed?
Regardless, you need to reduce the cache time. You may have to check the cache in the component that created the feed and another in the module where it is displayed.
