Nope. This is from the PHP manual: "Session data is usually stored after your script terminated without the need to call session_write_close(), but as session data is locked to prevent concurrent writes only one script may operate on a session at any time. When using framesets together with sessions you will experience the frames loading one by one due to this locking. You can reduce the time needed to load all the frames by ending the session as soon as all changes to session variables are done." This kind of thing you can see when you login. Most often the left frame will be half loaded before the right frame has even began to show, this isn't because the left frame is faster, it's because PHP is suspending access to the session file while the left frame has it open. > I sure wish I could've known that this setup didn't work, since I've been > running it for the past 3 (4?) years without any trouble. :) You've been lucky. A lot of the times, session information gets corrupted because user a logs in, then user b logs in from the same browser/new tab/new window, the cookie information points user b to the session file of user a, then the preferences for user b get loaded over the top of the session information for user a... the fact it hasn't happened to you yet is a good thing, and as Paul mention, something we are working on trying to fix. -- Jonathan Angliss <[EMAIL PROTECTED]> ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
