v1_8_6_287 - Show latest stable - 0 notes - Class: CGI::Session::FileStore

new(session, option={}) public

Create a new FileStore 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 FileStore 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 FileStore file. Defaults to the empty string.
suffix:	the prefix to add to the session id when generating the filename for this session’s FileStore file. Defaults to the empty string.

This session’s FileStore file will be created if it does not exist, or opened if it does.
