problem with session storage in db

Hi, We're using MySQL 3.23 with the latest versions of PHP. When changing the content of a session variable, PHP is not fast enough in storing that data in the db until the browser loads the next page (for example when redirecting the browser with Location:) that the next page contains that data. Is there any solutions for this? I understand that this does not happen if you use a local file storage for this, but using an external db, this is a problem. The reason for using an external db is for building a really scalale web site with sessions being used on a load balancing cluster. The easy solution would be to lock the table for each write to the session table, but this would really slow things down. Not usable in this context. One can make PHP sleep for a second before redirecting the browser as well, but this does not guarantee that the data has been written yet either. -- patrik wallstrom | f o o d f i g h t tel: +46-8-6188428 | s t o c k h o l m gsm: +46-708405080 | - - - - - - - - - fax: +46-859827151 |
