URL Mapping is a mechanism by which you can change the displayed url in address bar.
Example
Step1: Add Mapping URL in web.config file.<system.web>
<urlMappings enabled="true">
<add url="~/Department.aspx" mappedUrl=" oldforms/frmDept.aspx"/>
<add url="~/Employee.aspx" mappedUrl=" oldforms/frmEmployee.aspx"/>
<add url="~/Product.aspx" mappedUrl="& gt;
</urlMappings></system.web>
Step2: Change the URL in .aspx file
<a href="Department.aspx">Department</a><br />
<a href="Product.aspx">Product</a><br />
<a href="Employee.aspx">Employee</a>
