- xrds_specified_location(+URL, -XRDSLocation) is nondet[multifile, library(http/yadis)]
- Hook that allows for specifying locations of XRDS documents. For
example, Google does not reply to Yadis discovery messages. We
can fake it does using:
yadis:xrds_specified_location('http://google.com/', 'https://www.google.com/accounts/o8/id').If this hook succeeds with XRDSLocation bound to
-(minus), we assume there is no XRDS document associated to URL. This can be used to avoid retrieving misleading or broken XRDS documents. - yadis:xrds_specified_location(+Server, -XRDSLocation)[multifile, 'openid.pl']
- Hacks to deal with broken Yadis support.
- Google does not support Yadis discovery, but does have an XRSD document, so we fake its location.
- stackexchange.com serves an OP Identifier Element instead of an Claimed Identifier Element when doing Yadis discovery on the real OpenID.
