RFC 1630 specification lists the "file" scheme as being for "local file access", and RFC 1738 says they are for "host-specific file names" and points out that "The file URL scheme is unusual in that it does not specify an Internet protocol or access method for such files; as such, its utility in network protocols between hosts is limited." Presumably a hostname in such a URI would require that some host-specific protocol be used (but this should be an access protocol like SMB or NFS, not a transfer protocol like FTP).
It seems pretty clear that randomly interpreting particular host names to imply a specific remote-access protocol like FTP is bogus. regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 DjangoCon US September 7-9, 2010 http://djangocon.us/ See Python Video! http://python.mirocommunity.org/ Holden Web LLC http://www.holdenweb.com/ _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
