I'm using 1.2.1GA

I noticed two GET parameters [cid] and [clr] and it seems that the second 
one is used in order to check whether the conversation is long running or not. But I do not understand how does the postback work - tried to 
print out the request parameters but nothing about cid/clr:


  | <c:forEach var="n" items="#{facesContext.externalContext.requestParameterMap}"> 
  | 	#{n.key} = #{n.value}<br/>			
  | </c:forEach>

How does the conversationId sent with that view ?
I checked seam-booking demo with back button - the page is restored, but
seems it's from browser's cache - server.log didn't included an extra request trace.

As a GET parameter ?
