XMLHTTP Operations
Two of the HTML Components (HTCs) provided by the Commerce Server Business Desk Framework provide a special feature known as XMLHTTP operations. These HTCs are the ListSheet HTC and the TreeView HTC. The purpose of this feature is to enhance the performance of these HTCs by providing a structured mechanism in which the HTC can request additional XML data from the server in such a way that the page will not need to be reloaded.
In addition, there are a number of routines in the framework for doing XMLHTTP operations on a page outside the context of the ListSheet and TreeView HTCs. These routines can be used to implement pages that save information to the server without having to reload the entire page. Examples include many of the edit pages in the Campaign Manager module.
For more information about XMLHTTP operations and the fetch pages upon which they rely, see XMLHTTP Operations and Fetch Pages.
For more information about the configuration of XMLHTTP operations within the XML meta-data data-islands for the ListSheet HTC and the TreeView HTC, see ListSheet Configuration and TreeView Configuration, respectively.
