         This case is considered as an error by rfc2396.
         but several options are left to the implementation.
         So the result is implementation specific.
         see section 5.2, step 6.g

         "Implementations may handle this error
         by retaining these components in the resolved path (i.e.,
         treating them as part of the final URI), by removing them from
         the resolved path (i.e., discarding relative levels above the
         root), or by avoiding traversal of the reference."
