| /** |
| * URL normalizer performing basic normalizations: |
| * <ul> |
| * <li>remove default ports, e.g., port 80 for <code>http://</code> URLs</li> |
| * <li>remove needless slashes and dot segments in the path component</li> |
| * <li>remove anchors</li> |
| * <li>use percent-encoding (only) where needed</li> |
| * </ul> |
| * |
| * E.g., |
| * <code>https://www.example.org/a/../b//./select%2Dlang.php?lang=espaƱol#anchor<code> |
| * is normalized to <code>https://www.example.org/b/select-lang.php?lang=espa%C3%B1ol</code> |
| * |
| * Optional and configurable normalizations are: |
| * <ul> |
| * <li>convert Internationalized Domain Names (IDNs) uniquely either to the |
| * ASCII (Punycode) or Unicode representation, see property |
| * <code>urlnormalizer.basic.host.idn</code></li> |
| * <li>remove a trailing dot from host names, see property |
| * <code>urlnormalizer.basic.host.trim-trailing-dot</code></li> |
| * </ul> |
