Feeds should not be served with the 'foo' media type

The web server is reporting an unexpected MIME type for a feed. Although we tried to parse it as a feed, aggregators may well report this as an error and act as if the user had pointed them at something other than a feed.

RSS feeds should be served as application/rss+xml (RSS 1.0 is an RDF format, so it may be served as application/rdf+xml instead). Atom feeds should use application/atom+xml. Alternatively, for compatibility with widely-deployed web browsers, any of these feeds can use one of the more general XML types - preferably application/xml.

Use the appropriate MIME type for your feed.

• For static content served with Apache, use the AddType directive.
• For static content served with Microsoft IIS, add a MIME type.
• Other information can be found here or in the documentation provided by your server.
