In theory yes. But most likely your browser would have timed out by then, and whether the second page continues to execute after browser has timed out depends on the ignore_user_abort setting. > So the only way for the user to be able to do anything while the first > page is at work is to get a new session id for each new window? Depends on how you structure your application. You're using the session data to keep track of the state of your application? For that to be feasible the state can only be changed by one process at any one time. PHP's session handling takes care of that little detail for you. What you need to do is to minimise the time that your application spends "in-between" states ie where the state is undefined. The state is undefined when the session is open (ie session_start()) and will remain so until you have finalised it by writing what you need into the $_SESSION and doing session_write_close(). So, if your lengthy processing bit is not related to your application state then do your application state stuff first, update $_SESSION, close session, then do your lengthy processing. Now if you need to update $_SESSION after your lengthy process you can always do another session_start(). However if your other pages depends on the result of the lengthy process then this is no getting around the fact that access to those pages have to be blocked until the process is finished. > In such a case, is there any way to pass information between sets of > session variables in such a case?

If you really really want to pass info, you have to be more specific on how, where and when you want this 'passing' to take place. -- Jason Wong -> Gremlins Associates -> www.gremlins.biz Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * ------------------------------------------ Search the list archives before you post http://marc.theaimsgroup.com/?l=php-general ------------------------------------------ /* Any given program will expand to fill available memory. */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
