You didn't get the point. Suppose you want to print out how many users are browsing the site at the moment. You would have to count the active sessions. Unfortunately there's no way to do that. A quick workaround would be to use a variable global to all the sessions, add 1 to it for every new session and register a cleanup function for the session that substract 1 to the variable. The variable would then count the active sessions, which roughly estimates how many users are browsing the site. Now, in this simple example i could just pickle the variable and store it on disk using dbm, mysql or whatever. But 1. what about unpickable objects? are all objects pickable? 2. is this a bit inefficient? You would have to read, unpickle and repickle the variable every time a new session begins or expires, or read and unpickle it on every request! 3. I'm lazy... anybody did this before and can post the code? ^_^
