This plugin provides a host-meta – file for WordPress (RFC:

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. ‹›) 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.
