This plugin provides a host-meta – file for WordPress (RFC: http://tools.ietf.org/html/rfc6415).
From the RFC:
> Web-based protocols often require the discovery of host policy or
> metadata, where host is not a single resource but the entity
> controlling the collection of resources identified by URIs with a
> common host as defined. While these protocols have a
> wide range of metadata needs, they often define metadata that is
> concise, has simple syntax requirements, and can benefit from storing
> its metadata in a common location used by other related protocols.
> Because there is no URI or a resource available to describe a host,
> many of the methods used for associating per-resource metadata (such
> as HTTP headers) are not available. This often leads to the
> overloading of the root HTTP resource (e.g. ‘http://example.com/’)
> with host metadata that is not specific to the root resource (e.g. a
> home page or web application), and which often has nothing to do it.
> This memo registers the “well-known” URI suffix ‘host-meta’ in the
> Well-Known URI Registry established by,
> and specifies a simple, general-purpose metadata document for hosts,
> to be used by multiple Web-based protocols.
