Some browsers (typically older versions of IE) have trouble keeping track of a URL containing a hash fragment if there is a redirect involved, this solves that problem.
Simply have your server handle the final redirect:
http://example.com/redirect?d=http%3A%2F%2Fexample.com&h=hashValue
or alternatively
http://example.com/redirect?u=http%3A%2F%2Fexample.com%23hashValue
