When i see the code of most famous CMS and forums; i see they used to save the sessions in DB instead of Hard Disk.
While we can specify the save location of sessions by “session save path” directive in the user’s hosting space on server; to avoid the session conflict problem in share host servers, while they still persist on saving sessions in DB?
in YII, it seems the default is saving the sessions on hard Disk.
Managing the sessions on hard disk seems to have lower load on server, but i am just scared to do that.
