{- These (78-81) are some awkward test cases thrown up by a question on the URI list:
     http://lists.w3.org/Archives/Public/uri/2005Jul/0013
   Mote that RFC 3986 discards path segents after the final '/' only when merging two
   paths - otherwise the final segment in the base URI is mnaintained.  This leads to
   difficulty in constructinmg a reversible relativeTo/relativeFrom pair of functions.

-- $Revision: 1.8 $
-- $Log: URITest.hs,v $
-- Revision 1.81 2012/08/01           aaronfriel
-- Added additional test case for the "xip.io" service style URLs and absolute URLs prefixed with ipv4 addresses.
--
-- Revision 1.8  2005/07/19 22:01:27  gklyne
-- Added some additional test cases raised by discussion on URI@w3.org mailing list about 2005-07-19.  The test p[roposed by this discussion exposed a subtle bug in relativeFrom not being an exact inverse of relativeTo.
--
-- Revision 1.7  2005/06/06 16:31:44  gklyne
-- Added two new test cases.
--
-- Revision 1.6  2005/05/31 17:18:36  gklyne
-- Added some additional test cases triggered by URI-list discussions.
--
-- Revision 1.5  2005/04/07 11:09:37  gklyne
-- Added test cases for alternate parsing functions (including deprecated 'parseabsoluteURI')
--
-- Revision 1.4  2005/04/05 12:47:32  gklyne

--
-- Revision 1.3  2004/11/05 17:29:09  gklyne

-- specification (password "anonymous" is no longer a special case).
-- Updated URI test module to use function 'escapeURIString'.
-- (Should unEscapeString be similarly updated?)
--
-- Revision 1.2  2004/10/27 13:06:55  gklyne
-- Updated URI module function names per:
-- http://www.haskell.org//pipermail/cvs-libraries/2004-October/002916.html

-- Revision 1.10  2004/04/20 14:54:13  graham
-- Fix up test cases related to port number in authority,
-- and add some more URI decomposition tests.
--
-- Revision 1.9  2004/04/07 15:06:17  graham
-- Add extra test case
-- Revise syntax in line with changes to RFC2396bis
--
-- Revision 1.8  2004/03/17 14:34:58  graham
-- Add Network.HTTP files to CVS
