tag and hiding parameters in the link

[[EMAIL PROTECTED]]

Hi all,

I use <s:url.../> tag to create a link to an action and <s:param.../> tag to
pass one variable "lang", like this:

<s:url id="editUrl" namespace="/ssicsi" action="edit">
 <s:param name="lang" value="fr"/>
</s:url>

I don't want the "lang=fr" to appear in the URL so I tried to do it by
including
 <s:param name="method" value="post"/>
in the <s:url.../> body or setting includeParams="none" in the <url> tag
like this
 <s:url id="editUrl" namespace="/ssicsi" action="edit" includeParams="none">
  ...
 </s:url>
but neither works. I use struts 2.0.11.

Can anyone help me how to make it?

Thanks.
