If the feed was redirected from its original URL, status will contain the redirect status code, not the final status code.
If status is 301, the feed was permanently redirected to a new URL. Clients should update their address book to request the new URL from now on.
If status is 410, the feed is gone. Clients should stop polling the feed.
|status will only be present if the feed was retrieved from a web server. If the feed was parsed from a local file or from a string in memory, status will not be present.|
