Windows 8，由于Javascript应用程序中的xml缓存而无法更新应用程序数据

I am working on a windows 8 application in javascript. The application fetches a xml periodically from the server, parse the data and update the data in application. When the application is updated, the application is not displaying the latest data instead the previously fetched result is displayed. This may be due to caching of xml data but am not sure about the issue.I am working on a windows 8 application in java
