                 URL: https://issues.shibboleth.net/jira/browse/IDP-172
             Project: Identity Provider
          Issue Type: Task

A URL starting file:/// is taken to mean an "absolute" file url.  The semantic for handling this is "take everything after the third '/' as pass it to the filesystem, telling the filesystem that this is an absolute path.  On Unix system this means adding a leading '/', on non Unix systems the behavior differs but you can often pass the name in directly since absolute and relative names can be sensed in other ways (although to be absolutely accurate there is significant further munging needed to remove things like ':' in device delimiters).

Because of the confusions between '\' as a URL delimiter and '\' as a filesystem delimiter we get confused about this, often getting things wrong.  So watch it when we do the V3 installer.
