Controller (MVC) should open page in an new Browser Window

Hi,

I would like to open a page in a new browser window out of a controller.

In the end there are too pages. The first one is the only view of the main controller. It contains a list of documents which can be selected. By clicking on a document another window should open containing a pdf document (using PDF Plugin of IE).

For security reasons it is not possible to use javascript. The URL of the pdf document is not allowed to be displayed anywhere in the browser. That is why I would like to realize a frameset one the second page. The second page is a simple BSP page not a view.

I need something like:

navigation->goto_page_open_in_new_window( url = 'myPage.htm' )

Thanks for your help.
