What is the correct MIME type to use for an RSS feed?

Question

Is one MIME type preferable to ensure compatibility with RSS readers and other scrapers?

The options seem to be:

• text/xml
• text/rss+xml

Interestingly Stackoverflow is using text/html.

Answer 1

Neither. It's application/rss+xml http://www.rssboard.org/rss-mime-type-application.txt
