Kindly let me know how can we find out how many have logged (present time)into zope under the same URl.If there is an dtml-tag for this kindly give me that.
Obviously, you do not know yet how logging in works: HTTP is a stateless protocol. There is not such concept "currently being logged in". Zope does not know, who is or how many are currently "logged in". Instead, Zopes sees a sequence of requests, all independent from one another (from Zope's point of view). Some requests contain authentication information. You probably tend to say, that these requests are requests from logged in users. However, the authentication information is maintained by the browser. Zope has not information whatsoever about when the browser drops the authentication information (user logs off), e.g. because the browser is terminated. It therefore cannot tell, who currently is logged in. There is a cookie based authentication. For this form, there usually is a session/user record for logged in users on the server. The cookie identifies the associated session/user record. Again, Zope does not know, when the browser drops the cookie (user logs off), but it can force log off with an inactivity timeout. When the user does not access Zope for a specific time, it deletes the session/user record. When the cookie still exists, the next request using this record will require a new log in. With this authentication form, you can *estimate* the number of logged in users by counting the current session/user records. Dieter
