I would probably have the frame page itself be a simple entry point and just have it keep requesting your updated HTML content via an RPC and update your frame's innerHTML to set the content to the HTML returned by the call, you can probably even get it set to only return the "next" chunk of HTML instead of the whole page by remember some file marker (byte count?) that tells the servlet where the last read left off at. I think this would probably fix your scrollbar issue as well since you're not reloading the page with each request, instead just resetting some innerHTML.
