question about findForward()

I'm having trouble explaining what I want but I'll have a go
of it anyway...

I'm in a "Save" action as a result of the POSTing of a form
via a <html:cancel> button.  I do the test:

    if (isCancelled(request)) {}

and detect the cancel.  I'd like to go to another Action but
I don't want to "propagate" the POST.  I want it to be a GET
where the input ActionForm is empty.

I'm calling
     ActionForward forward = mapping.findForward(forwardName);
     return forward;
to go to the new action but it propagates the POST.

Is there anyway turn the POST into a GET?
Should I just call form.reset() manually?


I hope this makes sense.
Kevin.

Thank you both.

The strange thing is, I tried the redirect attribute before I posted
my question last night.  I must have done something wrong because
I tried it again this morning after seeing your responses and it
works just as you said.  As a note, it seems to work the same
whether I reset() the form or not (it is in session scope).

Emmanuel, why do you say that I need to call reset()?

Thanks again,
Kevin

 You need a redirection. In a redirection, the request (who containt the form) is not propagate. Just put in forward declaration :
<forward name="toto" path="/path_to_toto.jsp" redirect="true"/>
If your form is stored in session scope, you need to call reset();
