-<p>The mapping format is as follows.
+<p>
+To use <tt>TUrlMapping</tt>, one must set the <tt>UrlManager</tt> property of the <tt>THttpRequest</tt> module as the <tt>TUrlMapping</tt> module ID. See following for an example,
 <com:TTextHighlighter Language="xml" CssClass="source">
-<module id="friendly-url" class="System.Web.TUrlMapping">
-  <url serviceParameter="ClassName" pattern="pattern" parameters.id="subpattern" />
-</module>
+<modules>
+    <module id="request" class="THttpRequest" UrlManager="friendly-url" />
+    <module id="friendly-url" class="System.Web.TUrlMapping">
+        <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>
+</modules>
 </com:TTextHighlighter>
 </p>
 
-<p>The <tt>ServiceParameter</tt> and <tt>ServiceID</tt>
- (the default ID is 'page') set the service parameter and service ID, respectively, of
- the <a href="?page=Fundamentals.Modules">Request module</a>.
- The service parameter for the <tt>TPageService</tt> service is the
- Page class name, e.g., for an URL "index.php?page=Home", "page" is the service ID and the service
- parameter is "Home". Other services may use the service parameter and ID differently.
-See <a href="?page=Fundamentals.Services">Services</a> for further details.

+The above example is part of the application configuration of the <tt>blog</tt> demo in the PRADO release. It enables recognition of the following URL formats:
+</p>
+<ul>
+  <li><tt>/index.php/post/123</tt> is recognized as <tt>/index.php?page=Posts.ViewPost&id=123</tt></li>
+  <li><tt>/index.php/archive/200605</tt> is recognized as <tt>/index.php?page=Posts.ListPost&time=200605</tt></li>
+  <li><tt>/index.php/category/2</tt> is recognized as <tt>/index.php?page=Posts.ListPost&cat=2</tt></li>
+</ul>
+
+<p>
+The <tt>ServiceParameter</tt> and <tt>ServiceID</tt> (the default ID is 'page') set the service parameter and service ID, respectively, of the <a href="?page=Fundamentals.Modules">Request module</a>. The service parameter for the <tt>TPageService</tt> service is the Page class name, e.g., for an URL "index.php?page=Home", "page" is the service ID and the service parameter is "Home". Other services may use the service parameter and ID differently. See <a href="?page=Fundamentals.Services">Services</a> for further details.

+<h2>Specifying URL Patterns</h2>
+<p>
+<tt>TUrlMapping</tt> enables recognition of customized URL formats based on a list prespecified of URL patterns. Each pattern is specified in a <tt>&lt;url&gt;</tt> tag.

  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.

+<h2>Constructing Customized URLs</h2>
+<p>
+Since version 3.0.6, <tt>TUrlMapping</tt> starts to support constructing customized URL formats. This is achieved by allowing users to extend <tt>TUrlMapping</tt> class and override the <tt>constructUrl</tt> method. In the applications, users can still use <tt>THttpRequest.constructUrl()</tt> or <tt>TPageService.constructUrl()</tt> to generate PRADO-recognizable URLS. The actual URL construction work is ultimately delegated to the <tt>TUrlMapping.constructUrl()</tt>, provided it is implemented.
