Annoying refresh problem

When I create a case in RT, it’s pretty annoying that I cannot refresh
the case anywhere. And if I do refresh, the browser tell me that it
contains POSTDATA, thus I would resend the data when I click refresh in
my browser.
The problem could be fixed with one of these solutions:

  1. Better form post-programming, e.g. using a separate re-direct page
    like most known forums do nowadays
  2. A button to press for refreshing a page (typically on Create.html,
    or Update.html)
