Yadis discovery protocol implementation.
Yadis discovery protocol returns a Yadis Resource Descriptor (XRDS) document associated with a Yadis Identifier (YadisID)
YadisIDs can be any type of identifiers that are resolvable to a URL form, and in addition the URL form uses a HTTP or a HTTPS schema. Such an URL is defined by the Yadis speficification as a YadisURL. This functionality is implemented by the YadisURL helper class.
The discovery of the XRDS document is performed by the discover method on a YadisUrl.
Internal parameters used during the discovery process :
- max redirects (default 10): maximum number of redirects to be followed for YadisURL
