[Twisted-web] IRedirectAfterPost

[vicky]

Hi,

      I'm having some problems with iformless.IRedirectAfterPost.  The first
time I post my form, I see my results' page with the data posted.  But when
I use "back" on my browser and I try to post my form again, the
IRedirectAfterPost doesn't seem to be done.  It bring me back the page with
the form posted (no data in my fields). Only once out of two my form is
posted correctly even if I'm using the back button.  I didn't find out how
to fix it.
