42   * Query aware virtual uri mapping implementation that uses regular expressions in fromURI/toURI. When using regular expression in <code>fromURI</code>, <code>toURI</code> can contain references to the regexp matches. For example:
43   *
44   * <pre>
45   * fromURI=/products/([0-9A-Z]+)\.html\?available(true|false)
46   * toURI=/product/detail.html?productId=$1&available=$2
47   * </pre>
48   *
49   * @deprecated since 5.5.6, regex URI mapping has been relocated to the virtual-uri module (see MAGNOLIA-7016).
