Here is an example of listing folder contents with rs:Command= ListChildren
command to a SharePoint Report Server.

The syntax used for URL addressing for this example is http://hodentekwin7/_
vti_bin/ReportServer/?http%3a%2f%2fhodentekwin7%2fDocuments%2fFirstFo
lder&rs:Command=ListChildren .

Reporting Services extensions
SQL Server Reporting Services uses extensions to modularize the types of input/
output it accepts for the following tasks:

• Authentication
• Data processing
• Report processing
• Rendering
• Delivery
• Custom report processing

A Report Server requires at least one extension from authentication, data processing,
and rendering.

However there are default extensions that can be used without the necessity to create
custom extensions. Here are details of the defaults taken from the Microsoft.com
link http://msdn.microsoft.com/en-us/library/ms157231.aspx .

Type Default

Authentication A default Report Server instance supports Windows

authentication, including impersonation and delegation
features if they are enabled in your domain.
