Refresh Jforum Portlet

Hi All,
 
I think there is a problem with the Jforum Portlet refresh.I mean that when a user enter his logging , the Jahia portail's display change and the label "user:" appears but it is not the case of the Jforum display.
I have to click on the Connexion link in order to refresh it.
The fact is that I can't manage the cache using the  following code as it's possible in the jsp files of the others portlets because the JForum portlet is constructed with .htm files.
 
 Long monDelay= new Long(0);
request.setAttribute("org.jahia.portletapi.CacheExpirationDelay",monDelay);
 
 
According to me, my problem is about the forum_list.htm file.
If you have an idea to help me
 
Thanks in advance
Fabrice
