Problem with frames and browser refresh

When the application logs in it sends controll from the LoginAction.do via struts to ProjectFrame.jsp. This jsp defines two frames.

My problem is that if the user clicks the browser refresh it is resubmitting the loginAction.do and relogging.

I'm sure this is something that other people have faced... but the search tool on this page isn't working for me. Any one have an idea how to deal with this.. Perhaps if I could change the url so that it said ProjectFrame.jsp instead of loginAction.do then the refresh wouldn't log back in.. but how to change that?
