Proper MIME media type for TAR files
<p>When working with TAR files, I've run across the MIME type</p>

<blockquote>
  <p>application/x-tar</p>
</blockquote>

<p>However I am not sure it is right, because</p>

<blockquote>
  <p>MIME types in the x- namespace are considered experimental</p>
</blockquote>

<p>and it seems odd to me for venerable TAR.</p>

<p>Are there any recent RFC about MIME and TAR ?
And what's about widespread HTTP server and browsers support ?</p>
