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.
