getting an RSS feed for an iTunes podcast

Attention

This is not a permanent solution to the problem of web pages for iTunes podcasts not providing a way of getting RSS feeds. It could stop working at any time.

Get the id number from the page's URL, for example 941907967 from https://itunes.apple.com/us/podcast/reply-all/id941907967, the page for Reply All. Visit the URL https://itunes.apple.com/lookup?id=foobar&entity=podcast, where foobar is the id number, for example https://itunes.apple.com/lookup?id=941907967&entity=podcast. This will return a JSON-formatted plain text document named 1.txt, which can be saved as a file with a json extension. The RSS feed URL will be the value for the feedUrl attribute, for example http://feeds.gimletmedia.com/hearreplyall.
