Subject Re: [Trinidad] Is it possible to PPR the tr:document?
Date Tue, 26 Feb 2008 19:36:17 GMT
For anyone who read this reply, please note that I was naive and
thought the URL hash would be sent to the server. It is not. So
refresh & bookmarking is still problematic, but back & forward can be
handled gracefully.
