Flex, Determining which server/domain a SWF is hosted on

situation
	Here’s a handy tip which can help you when deploying Flex applications on mulitple servers (such as a staging/production server). Basically you can listen for the Application tag to dispatch the applicationComplete event, grab the URL of the SWF using the loaderInfo.url property, and then use the URLUtil.getServerName() method to parse out the server name.

solution
	In prior version of Flex 4.0 use this: URLUtil.getServerName(Application.application.loaderInfo.url); In 4.0 use this: because Application is no longer available in 4.0 URLUtil.getServerName(FlexGlobals.topLevelApplication.url)
