Web Dynpro inside iFrame open URL same window

Hi,

In WebDynpro ABAP, not portal nor java, I have a public webdynpro app with an iFrame, inside that iFrame I have another private Webdynpro app which requires login. After login I would like to go to the private WebDynpro app, not inside the iFrame, but I want the private WebDynpro app to take over the entire window.

In a pure html link or javascript that would be '_top' target and I could include another iFrame with BSP and javascript to automatically redirect to the new URL.

How is this possible with WebDynpro, if even possible? Maybe an URL parameter in the Exit plug's url?

Thanks!
