I recently wanted to listen to a single episode of a podcast without adding it to any extra software, so I grabbed the URL and went to play it in my browser. Then, I looked it again and noticed something strange - it started with: https://pdst.fm/e/dts.podtrac.com/redirect.mp3/traffic.omny.fm/ So, while the podcast played in the background, I loaded it up in curl and fiddled with it a bit until I saw the following fly by as Location: headers.
