# cgi/session/pstore.rb - persistent storage of marshalled session data

# == Overview
|
|
#
|
|
# This file provides the CGI::Session::PStore class, which builds
|
|
# persistent of session data on top of the pstore library. See
|
|
# cgi/session.rb for more details on session storage managers.

# PStore-based session storage class.
|
|
#
|
|
# This builds upon the top-level PStore class provided by the
|
|
# library file pstore.rb. Session data is marshalled and stored
|
|
# in a file. File locking and transaction services are provided.
|

# Create a new CGI::Session::PStore instance
|

#
|
|
# This constructor is used internally by CGI::Session. The
|
|
# user does not generally need to call it directly.
|
|
#
|
|
# +session+ is the session for which this instance is being
|
|
# created. The session id must only contain alphanumeric
|
|
# characters; automatically generated session ids observe
|
|
# this requirement.
|
|
#
|
|
# +option+ is a hash of options for the initialiser. The
|
|
# following options are recognised:
|
|
#
|
|
# tmpdir:: the directory to use for storing the PStore
|
|
# file. Defaults to Dir::tmpdir (generally "/tmp"
|
|
# on Unix systems).
|
|
# prefix:: the prefix to add to the session id when generating
|
|
# the filename for this session's PStore file.
|
|
# Defaults to the empty string.
|
|
#
|
|
# This session's PStore file will be created if it does
|
|
# not exist, or opened if it does.
