Pavlos Christoforou wrote Right now a call to "FSSession.clear()" will nuke the data, but for compatibility with Anthony's SQLSession I will add the _force_new_session option. BTW why should someone want to change the Session ID?
Say you've got a site which stores user preferences and the like, and stores the user's session id in a cookie. When someone uses the same computer, and goes to the web site, they'll see something like <P>Welcome, <dtml-var "SESSION['name']"> (if you are not <dtml-var "SESSION['name']">, <a href="?_force_new_session=1">click here</a>)</P> This allows you to easily refresh the user's session. This is also useful if you allow a user to reattach to a session from a different PC. Anthony, who still needs to write up a bunch of use cases for sessions.
