What's this?

new(session, option={}) public

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 initializer. 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.
