/**
 * TUrlMapping Class
 *
 * The TUrlMapping module allows PRADO to construct and recognize URLs
 * based on specific patterns.
 *
 * TUrlMapping consists of a list of URL patterns which are used to match
 * against the currently requested URL. The first matching pattern will then
 * be used to decompose the URL into request parameters (accessible through
 * <code>$this->Request['paramname']</code>).
 *
 * The patterns can also be used to construct customized URLs. In this case,
 * the parameters in an applied pattern will be replaced with the corresponding
 * GET variable values.
 *
 * Since it is derived from {@link TUrlManager}, it should be configured globally
 * in the application configuration like the following,
 * <code>
 *  <module id="request" class="THttpRequest" UrlManager="friendly-url" />
 *  <module id="friendly-url" class="System.Web.TUrlMapping" EnableCustomUrl="true">
 *    <url ServiceParameter="Posts.ViewPost" pattern="post/{id}/" parameters.id="\d+" />
 *    <url ServiceParameter="Posts.ListPost" pattern="archive/{time}/" parameters.time="\d{6}" />
 *    <url ServiceParameter="Posts.ListPost" pattern="category/{cat}/" parameters.cat="\d+" />
 *  </module>
 * </code>
 *
 * In the above, each <tt>&lt;url&gt;</tt> element specifies a URL pattern represented
 * as a {@link TUrlMappingPattern} internally. You may create your own pattern classes
 * by extending {@link TUrlMappingPattern} and specifying the <tt>&lt;class&gt;</tt> attribute
 * in the element.
 *
 * The patterns can be also be specified in an external file using the {@link setConfigFile ConfigFile} property.
 *
 * The URL mapping are evaluated in order, only the first mapping that matches
 * the URL will be used. Cascaded mapping can be achieved by placing the URL mappings
 * in particular order. For example, placing the most specific mappings first.
 *
 * Only the PATH_INFO part of the URL is used to match the available patterns. The matching
 * is strict in the sense that the whole pattern must match the whole PATH_INFO of the URL.
 *
 * From PRADO v3.1.1, TUrlMapping also provides support for constructing URLs according to
 * the specified pattern. You may enable this functionality by setting {@link setEnableCustomUrl EnableCustomUrl} to true.
 * When you call THttpRequest::constructUrl() (or via TPageService::constructUrl()),
 * TUrlMapping will examine the available URL mapping patterns using their {@link TUrlMappingPattern::getServiceParameter ServiceParameter}
 * and {@link TUrlMappingPattern::getPattern Pattern} properties. A pattern is applied if its
 * {@link TUrlMappingPattern::getServiceParameter ServiceParameter} matches the service parameter passed
 * to constructUrl() and every parameter in the {@link getPattern Pattern} is found
 * in the GET variables.

/**
 * TUrlMappingPattern class.
 *
 * TUrlMappingPattern represents a pattern used to parse and construct URLs.
 * If the currently requested URL matches the pattern, it will alter
 * the THttpRequest parameters. If a constructUrl() call matches the pattern
 * parameters, the pattern will generate a valid URL. In both case, only the PATH_INFO
 * part of a URL is parsed/constructed using the pattern.
 *
 * To specify the pattern, set the {@link setPattern Pattern} property.
 * {@link setPattern Pattern} takes a string expression with
 * parameter names enclosed between a left brace '{' and a right brace '}'.
 * The patterns for each parameter can be set using {@link getParameters Parameters}
 * attribute collection. For example
 * <code>
 * <url ... pattern="articles/{year}/{month}/{day}"
 *          parameters.year="\d{4}" parameters.month="\d{2}" parameters.day="\d+" />
 * </code>
 *
 * In the above example, the pattern contains 3 parameters named "year",
 * "month" and "day". The pattern for these parameters are, respectively,
 * "\d{4}" (4 digits), "\d{2}" (2 digits) and "\d+" (1 or more digits).
 * Essentially, the <tt>Parameters</tt> attribute name and values are used
 * as substrings in replacing the placeholders in the <tt>Pattern</tt> string
 * to form a complete regular expression string.
 *
 * For more complicated patterns, one may specify the pattern using a regular expression
 * by {@link setRegularExpression RegularExpression}. For example, the above pattern
 * is equivalent to the following regular expression-based pattern:
 * <code>
 * #^articles/(?P<year>\d{4})/(?P<month>\d{2})\/(?P<day>\d+)$#u
 * </code>
 * The above regular expression used the "named group" feature available in PHP.
 * If you intended to use the <tt>RegularExpression</tt> property or
 * regular expressions in CDATA sections, notice that you need to escape the slash,
 * if you are using the slash as regular expressions delimiter.
 *
 * Thus, only an url that matches the pattern will be valid. For example,
 * a URL <tt>http://example.com/index.php/articles/2006/07/21</tt> will match the above pattern,
 * while <tt>http://example.com/index.php/articles/2006/07/hello</tt> will not
 * since the "day" parameter pattern is not satisfied.
 *
 * The parameter values are available through the <tt>THttpRequest</tt> instance (e.g.
 * <tt>$this->Request['year']</tt>).
 *
 * The {@link setServiceParameter ServiceParameter} and {@link setServiceID ServiceID}
 * (the default ID is 'page') set the service parameter and service id respectively.
 *
 * Since 3.1.4 you can also use simplyfied wildcard patterns to match multiple
 * ServiceParameters with a single rule. The pattern must contain the placeholder
 * {*} for the ServiceParameter. For example
 *
 * <url ServiceParameter="adminpages.*" pattern="admin/{*}" />
 *
 * This rule will match an URL like <tt>http://example.com/index.php/admin/edituser</tt>
 * and resolve it to the page Application.pages.admin.edituser. The wildcard matching
 * is non-recursive. That means you have to add a rule for every subdirectory you
 * want to access pages in:
 *
 * <url ServiceParameter="adminpages.users.*" pattern="useradmin/{*}" />
 *
 * It is still possible to define an explicit rule for a page in the wildcard path.
 * This rule has to preceed the wildcard rule.
 *
 * You can also use parameters with wildcard patterns. The parameters are then
 * available with every matching page:
 *
 * <url ServiceParameter="adminpages.*" pattern="admin/{*}/{id}" parameters.id="\d+" />
 *
 * To enable automatic parameter encoding in a path format from wildcard patterns you can set
 * {@setUrlFormat UrlFormat} to 'Path':
 *
 * <url ServiceParameter="adminpages.*" pattern="admin/{*}" UrlFormat="Path" />
 *
 * This will create and parse URLs of the form
 * <tt>.../index.php/admin/listuser/param1/value1/param2/value2</tt>.
 *
 * Use {@setUrlParamSeparator} to define another separator character between parameter
 * name and value. Parameter/value pairs are always separated by a '/'.
 *
 * <url ServiceParameter="adminpages.*" pattern="admin/{*}" UrlFormat="Path" UrlParamSeparator="-" />
 *
 * <tt>.../index.php/admin/listuser/param1-value1/param2-value2</tt>.
 *
 * Since 3.2.2 you can also add a list of "constants" parameters that can be used just
 * like the original "parameters" parameters, except that the supplied value will be treated
 * as a simple string constant instead of a regular expression. For example
 *
 * <url ServiceParameter="MyPage" pattern="/mypage/mypath/list/detail/{pageidx}" parameters.pageidx="\d+" constants.listtype="detailed"/>
 * <url ServiceParameter="MyPage" pattern="/mypage/mypath/list/summary/{pageidx}" parameters.pageidx="\d+" constants.listtype="summarized"/>
 *
 * These rules, when matched by the actual request, will make the application see a "lisstype" parameter present
 * (even through not supplied in the request) and equal to "detailed" or "summarized", depending on the friendly url matched.
 * The constants is practically a table-based validation and translation of specified, fixed-set parameter values.
