32 Implements an RFC 2396 compliant URI specification. See
|
|
|
33 <A HREF="http://ftp.ics.uci.edu/pub/ietf/uri/rfc2396.txt">this page</A>
|
|
|
34 for more information.
|
|
|
35
|
|
|
36 The implementation fails the spec on two counts: it doesn't insist
|
|
|
37 on a scheme being present in the Uri, and it doesn't implement the
|
|
|
38 "Relative References" support noted in section 5.2. The latter can
|
|
|
39 be found in tango.util.PathUtil instead.
|
|
|
40
|
|
|
41 Note that IRI support can be implied by assuming each of userinfo,
|
|
|
42 path, query, and fragment are UTF-8 encoded
|
|
|
43 (see <A HREF="http://www.w3.org/2001/Talks/0912-IUC-IRI/paper.html">
|
|
|
44 this page</A> for further details).
|
|
|
45
|
|
|
46 Use the UriView subset where you need a readonly perspective.
