I personally wouldn't do this, as DB_File needs write locking to maintain data integrity or they could become corrupt. I believe they were using it at RedHat, without problems, but if it were me, I wouldn't. I would stick with the default SDBM_File, which is really hard to corrupt, but you have the 1024 key/value byte limit, so its not good for storing large objects. If you really want DB_File, I would use a samba mount which I tested recently, and does support file locking very well. You may get away with using DB_File over NFS for session state if your site doesn't have frames, because you wouldn't expect concurrent access to $Session under those conditions. If you don't need Session_OnStart / Session_OnEnd events, then you can easily create a database backed Apache::Session solution, by setting $Session in global.asa Script_OnStart -- Josh _________________________________________________________________ Joshua Chamas Chamas Enterprises Inc.
