[Zope] Redirection to a special page based on user ID

Hello All, I am looking for some help in something I am trying to do. What I want is to present someone with a log-on page that will authenticate them against zope ID's and then redirec them to a page based on their ID. So basically something in terms of mr. john smith logs in to page www.xxxyyy.com/login.html When the system authenticates the login for jsmith it redirects him to a directory www.xxxyyy.com/somedir/jsmith/ Does someone know how to do this???? If you have some code and a detailed explenation it would be wonderful. Thank you Yury
