Is there a time limit for the resolved stream location URL?

[alexweinstein]

API Guide tells us that in order to get the streaming file location of a track, we should:

Send a GET request to stream_url and you will get a set of links with available transcodings which you can choose from.

This returns:

{
    "status": "302 - Found",
    "location": "https:\/\/cf-media.sndcdn.com..."
}

However, it seems that the location url expires after a few minutes, generating a 403.

My questions:

• What is the official length of time that the location url will last?
• Is there a way to extend it?
• Is there another way I should be getting the stream file url that doesn't expire?
