The URL mapping feature uses configuration information stored in web.config to remap incoming requests to a different URL. The remapping occurs prior to any other processing for the inbound request. Although the sample below demonstrates remapping a page request, any arbitrary file type can have its request remapped to a different URL.

At first you need to build a sitemap file Web.sitemap. The code as following:

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0">
<siteMapNode url="~/UrlMappingCsharp.aspx" title="Home Page" description="This is the home page" >
<siteMapNode url="~/Category.aspx" title="Categories" description="Information Categories" >
<siteMapNode title="News" description="News" url="~/News.aspx" />
<siteMapNode title="Games" description="Games" url="~/Games.aspx" />
<siteMapNode title="Health" description="Health" url="~/Health.aspx" />
</siteMapNode>
</siteMapNode>
</siteMap>

Secondly, please build a web.config file. The code is as following::

<?xml version="1.0" ?> <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<system.web>
<urlMappings enabled="true">
<add
url="~/News.aspx" mappedUrl="~/UrlMappingVB.aspx?category=news" />
<add
url="~/Category.aspx" mappedUrl="~/UrlMappingVB.aspx?category=default" />
<add
url="~/Games.aspx" mappedUrl="~/UrlMappingVB.aspx?category=games" />
<add
url="~/Health.aspx" mappedUrl="~/UrlMappingVB.aspx?category=health" />
</urlMappings>
</system.web>
</configuration>

The front end UrlMappingCsharp.aspx page looks something like this:

<table>
<tr>
<td><asp:SiteMapDataSource Runat=server ID="SiteMapDataSource1" />
<br /></td>
</tr>
<tr>
<td>
<asp:Label Runat=server Text="TreeView" id="Label3" ForeColor="#ff3366" />
<asp:TreeView ID="TreeView1" DataSourceID="SiteMapDataSource1" Runat=Server />
</td>
</tr>
<tr>
<td>
The current virtual path for the request is:<b> <% Response.Write(Request.Path)%></b>.
<br />
The value of the category querystring variable is:<b> <% Response.Write(Server.HtmlEncode(Request.QueryString("category")))%></b>.
<br />
However, the original path that was requested before it was remapped is:<b> <% Response.Write(Request.RawUrl)%></b>.
</td>
</tr>
</table>
