This module is used internally by ASP.NET to deal with unhandled exceptions. In the case of an exception, ASP.NET will return a page with a short error message (much as in a standard ASP.NET web page). The error message will be automatically formatted to the target device's expected markup. For WML devices, this will be a card deck. For HTML devices, this will be a page of HTML.

The automatically generated error messages are useful while debugging, but may not be shown to remote clients (depending on your settings in the web.config file). A better option is to write custom error pages and specify them using the web.config file before deploying a mobile web application.
