The 3GPP reference point associated with the HTTP interface provided by Converged Application Server is “Ut". This interface is primarily used for three purposes:

• As a Web-based User Interface for customer self-care and service configuration, potentially using HTML, XHTML or other presentation technologies.

• To support content indirection.

• To support XML Configuration Access Protocol (XCAP), required by Presence and Conference Control Protocol.

Converged Application Server provides HTTP support through its HTTP Servlet Container. Application developers may implement applications or components that support any or all of the above use cases for the “Ut" reference point.
