This is really about the browser and not about Spyce. If you can find out
how to do it any other language, such as PHP, then it will be exactly the
same in Spyce. It's a browser related issue, and how it responds to the
various headers in the HTTP response when you hit the back button. Many
browsers do not do a cache validation, and simply redisplay an "old"
version of the web page that you saw previously. I assume that the design
choice for this was in order to not resubmit twice to sites that ask you
please only "click once", otherwise they will get two purchase orders. You
can try to track the last page (or state) in the session, and then respond
appropriately if you get a request from a prior page. In general, this is
a good idea.
All the best,
