CKFinder How to Refresh explorer window

Hi,
Ive been looking at CKFinder to see if it meets my needs on a small project. However, one thing i need to do, and havent been able to, is to "ask" CKFinder to refresh the contents of the browser frame, from a javascript code.

I need to do this in order to "freshen" the contents after being heavily altered by the server. How can i do this ? Ive looked over all the code and dom model, and cant find how to emulate the working of the Refresh button.

Thanks
