RSS feeds give incorrect content types

[Otto42]

The RSS feeds are using a content type of "text/xml" which is not the standard. They should be using "application/rss+xml" instead.

Patch for trunk attached.

Change text/xml to application/rss+xml in the various rss feeds

[ryan]

I think Firefox and IE fixed the problems where changing to application/* would cause a download. This is probably safe to do now.

IE6 still downloads.

I think this topic regularly comes up, and I don't recall real benefit being demonstrated.

I recall that "application/xml" works on IE6, IE7 and Firefox.

Otto42 is there now a "standard"? MarkJ commented on a wp-testers thread in January, "Nah, text/xml is fine for RSS 2.0 AFAIK application/rss+xml has been
proposed but not standardized. ​http://www.rssboard.org/rss-mime-type-application.txt "

[Otto42]

Depends on how you define "standard". It has yet to be registered with IANA and such, but the feed validator wants application/rss+xml:
​http://feedvalidator.org/docs/warning/UnexpectedContentType.html

The use of application/xml and/or text/xml, while technically correct, was only to be compatible with IE6 and to allow the feed to display instead of to download. All major feed readers work with, and prefer, the more specific MIME types of rdf+xml, rss+xml, atom+xml, and so on.

I'm getting:

Content-Type: application/rss+xml; charset=UTF-8

and:

Content-Type: application/atom+xml; charset=UTF-8
