I am trying to do url mapping to show a url in a user friendly way.
This is how the actual url looks : www.abc.com/folder1/folder2/webpage.aspx

I would like to display the url more like this: www.abc.com/webpage.aspx

How do I achieve this? Url mapping doesn't seem to work as it thorws a Http 404 file not found error when I do the url mapping.

Here is how I mapped:

<urlMappings enabled="true">
      <add url="~/webpage.aspx"
         mappedUrl="http://www.abc.com/folder1/folder2/webpage.aspx" />
    </urlMappings>

Please help.
