Subject Re: Persisting data across authenticate <-> authorize ?
Date Tue, 14 Dec 2004 04:03:35 GMT
adding TTL to DirDB would not be difficult, using the filesystem's timestamps,
and if the files are kept in a tmpfs, or even just deleted before the
filesystem syncs,
there's no disk traffic.  

in my opinion, the simplicity of using the file system for persistence is most
appealing.  I keep repeating myself.
