Re: Sessions and redundant servers

G'day folks, Here's a theoretical question for those of you using PHP's inbuilt session facilities... How do you "keep" your variables across redundant servers? Or, isn't anybody out there hosting PHP-based services on grouped servers? My question may reflect a lack of understanding on just how PHP's sessions work, but (bear with me a moment) I thought that session variables were simply stored in a local file-store (default: /tmp). Are people using NFS-shared directories, rsync (or some other method of keeping such areas synchronised), or are all "redundant" sites using home-grown session handling? Ciao.

Our own experience is that the PHP method to define custom session handlers is broken - 'write' doesn't work. At least in earlier versions (4.0.0, 4.0.1, for sure). We've no real need to go back, because we're written our own which server our purpose just fine. Even if you're working on just one server, it's often handy to be able to do an SQL call to 'view' some of the raw session data.
