Hiding POSTed parameters in v2

Question

Hi:
I have a portal which contains tabbed pages. My problem is that within those tabbed pages I have jsp portlets which contain forms. When I submit the form, the data gets posted correctly, but when I change to another tabbed page, all the form variables are submitted in the URL to the new page. How do I prevent POSTed form variables from being added to the URL??
Regards

I'm using 9iAS 9.0.2
I used an example from PDK January
here is the JSP (bank.jsp):
<%@page import="java.util.*, oracle.portal.provider.v2.*" %>
<%@page import="oracle.portal.provider.v2.http.HttpCommonConstants" %>
<%@page import="oracle.portal.provider.v2.render.PortletRendererUtil" %>
<%@page import="oracle.portal.provider.v2.render.PortletRenderRequest" %>
<%@page import="oracle.portal.provider.v2.render.http.HttpPortletRendererUtil" %>
<%
String paramAmount = "Amount";
String paramAction = "Action";
PortletRenderRequest portletRequest =
(PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
%>
<b>This portlet shows how to use the passUrlParams flag and
unqualified, transient parameters to perform a portlet action.</b>
// The account transfer is performed by submitting the following form
<form method="POST" action="<%= HttpPortletRendererUtil.htmlFormActionLink(
request,PortletRendererUtil.PAGE_LINK) %>">
<%= HttpPortletRendererUtil.htmlFormHiddenFields(request,PortletRendererUtil.PAGE_LINK) %>
<table>
<tr>
<td>
<b>Amount $</b>
</td>
<td>
<input type="text" size="20" name="<%= paramAmount %>" value="">
</td>
</tr>
</table>
<br>
<INPUT TYPE=submit name="<%= paramAction %>" Value="Transfer">
</form>
// Parse the inputs to see if a transfer should be performed
<%
if (portletRequest.getParameter(paramAction) != null)
String submittedAmount = portletRequest.getParameter(paramAmount);
if (submittedAmount == null || submittedAmount.trim().length() == 0)
%>
<b>Please specify an amount!</b>
<%
else
try
double amount = Double.valueOf(submittedAmount).doubleValue();
if (amount != 0)
%>
<b>Successfully transferred $<%=submittedAmount%>.</b>
<%
catch (NumberFormatException e)
%>
<b>Invalid amount.</b>
<%
%>
here is my provider.xml:

When I press the submit button, the transient parameters are passed, but when I refresh the page the transient parameters are also passed.
When I make two TAB pages in the portal, and navigate between them, the behavior is the same.
Here is my URL after opening the tab page in a new navigator window:
http://portal2.eurotrend.hu:7777/portal/page?_pageid=73,31262,73_35033&_dad=portal&_schema=PORTAL&Amount=50&Action=Transfer
You can see the transient parameters in the URL!
I click the tab after submit.
This happens in IE 5.5 and IE 6.0
Thanks in advance!
