The HTTP status code that was returned by the web server when the feed was fetched.
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.
