When storing sessions, specify the name of the directory or DBM file to use. The file extensions of .db, or .gdbm (depending on the DBM implementation used) will be appended; if the default file-based sessions are used, then it is the name of the directory.

Can be an absolute path name if desired.
It is possible for multiple catalogs to share the same session file, and very possible for multiple MiniVend servers to serve the same catalogs. If you are serving a massively busy store, multiple parallel MiniVend servers can share the same NFS-based file system and serve users in a ``ping-pong'' fashion using the file-based sessions. On very, very, large systems you might want to change the level of directory hashing -- by default only 48 * 48 hashing is done. See the source for SessionFile.pm -- if you can't find the setting you have no business running that large a site. 8-)
