Whenever a link is clicked or a form submitted (or a new page loaded 
via JavaScript), htmlunit will return a new Page object which contains 
the updated content.  If you continuously refer to the "original" Page 
object, you will only see the original content loaded on that page.  
See below for comments on where new pages are being returned (that 
you're ignoring) in the code.

I don't have much experience with using frames, but I'm pretty sure 
they're going to work the same way (except that you may only get 
updates to individual frames instead of the whole frameset document).

New page is returned here (ignored).

New page is returned here (ignored).

This is not necessary.  Htmlunit will block until the page is fully 
loaded.

This is an old copy of the page (frameset) you're using here.

Still using an old copy of the page.

Old copy.

Old copy.
