/well-known-uris/

This plugin enables « Well-Known URIs » support for WordPress (RFC 5785: http://tools.ietf.org/html/rfc5785).

From the RFC:

It is increasingly common for Web-based protocols to require the discovery of policy or other information about a host (« site-wide metadata ») before making a request. For example, the Robots Exclusion Protocol http://www.robotstxt.org/ specifies a way for automated processes to obtain permission to access resources; likewise, the Platform for Privacy Preferences tells user-agents how to discover privacy policy beforehand.

While there are several ways to access per-resource metadata (e.g., HTTP headers, WebDAV’s PROPFIND [RFC4918]), the perceived overhead (either in terms of client-perceived latency and/or deployment difficulties) associated with them often precludes their use in these scenarios.

When this happens, it is common to designate a « well-known location » for such data, so that it can be easily located. However, this approach has the drawback of risking collisions, both with other such designated « well-known locations » and with pre-existing resources.

To address this, this memo defines a path prefix in HTTP(S) URIs for these « well-known locations », « /.well-known/ ». Future specifications that need to define a resource for such site-wide metadata can register their use to avoid collisions and minimise impingement upon sites’ URI space.

You will need ‘manage_options’ capability in order to use the Settings page for this plugin.
