feed and rss protocols format

What are rss: and feed: links ?

Addresses like feed:http://example.org/rss.xml are typical feed protocol URI. They are used (at the moment of this writing) by feed readers/aggregators and other utilities related to feed processing.

These two protocols (feed and rss) allow syndication of feeds (like RSS or Atom) into your feed reader/aggregator software (like WinRSS, Vox Lite, FeedReader, ...).

<feedurl>

The <feedurl> part of the URL is the address of any valid feed, for instance, an http file. As with current web browsers, http: is the default protocol:

feed://example.org/rss.xml

Other protocols can be used, like network shared resources or local filesystem files. Use their corresponding syntax to form a valid feed: URI:

feed:file:///c|/my%20documents/news.xml (this is a Windows file)

feed://ftp://user:password@ftp.host.com/path/index.xml (FTP file transfer protocol)

feed://file://\\server\share\index.xml (a Windows networked file)

feed:file:///server/share/index.xml (another valid network format)
