HTTP Status Code 308 (Permanent Redirect) to Proposed Standard
status-change-http-status-code-308-ps-01

In 2012, when RFC 7238 was approved, we went for Experimental because it was,
indeed, an experiment.  Since then, it has been implemented in Firefox and
Chrome, and Safari already supported it due to their default handling of 3xx +
Location.

The experiment is, therefore, over, and was a success.  This action moves RFC
7238 to the Standards Track, as Proposed Standard.  The document doesn't need
any changes, except to the boilerplate.  The RFC Editor will update the
boilerplate for Standards Track and will publish a new RFC that will obsolete
7238.
