I have a Podcast in the iTunes music store. I want to change the URL of the podcast XML feed. Here's how iTunes describes how to do it.
Changing Your Feed URL
Podcasters occasionally need to move their feed from one location to another. In this case, you should not remove your feed. If possible, you should set your web server to return a 301 error and redirect when receiving a request for the old feed. Doing so will cause both the iTunes Music Store and the iTunes clients that have subscribed to your podcast to pick up the new feed URL. Be sure to maintain the redirect for at least two weeks to ensure that most subscribers have attempted to download your most recent episode and have thereby received the new URL.
I have no idea how to implement this! Any help would be appreciated!
