  /*
    To update a RSS feed URL (it happens when editors want to change tags) we need to either:
      1. return a 301 redirect response for the old feed to the new feed
      2. use the <itunes:new-feed-url> tag in the new feed to point to the new URL

    We're using 301 redirects when we change tags, and the new-feed-url tag to tell Apple
    to update our feeds to use https.
