Arguments
Description
A new function that can be used to test if a component is running in Working Preview mode. The function returns .T. if the component is running in Working Preview. The previous technique that was used (`request.SERVER_PROTOCOL = "A5RES"`) can no longer be used, as Working Preview no longer relies on the special A5RES protocol.
