NAME

       CGI::Session::Driver::file - Default CGI::Session driver

SYNOPSIS

	   $s = new CGI::Session();
	   $s = new CGI::Session("driver:file", $sid);
	   $s = new CGI::Session("driver:file", $sid, {Directory=>'/tmp'});

DESCRIPTION

       When CGI::Session object is created without explicitly setting driver, file will be assumed.  file - driver will store session data in
       plain files, where each session will be stored in a separate file.

       Naming conventions of session files are defined by $CGI::Session::Driver::file::FileName global variable.  Default value of this variable
       is cgisess_%s, where %s will be replaced with respective session ID. Should you wish to set your own FileName template, do so before
       requesting for session object:

	   use CGI::Session::Driver::file; # This line is mandatory.
	   # Time passes...
	   $CGI::Session::Driver::file::FileName = "%s.dat";
	   $s = new CGI::Session();

       For backwards compatibility with 3.x, you can also use the variable name $CGI::Session::File::FileName, which will override the one above.

   DRIVER ARGUMENTS
       If you wish to specify a session directory, use the Directory option, which denotes location of the directory where session ids are to be
       kept. If Directory is not set, defaults to whatever File::Spec->tmpdir() returns.  So all the three lines in the SYNOPSIS section of this
       manual produce the same result on a UNIX machine.

       If specified Directory does not exist, all necessary directory hierarchy will be created.

       By default, sessions are created with a umask of 0660. If you wish to change the umask for a session, pass a UMask option with an octal
       representation of the umask you would like for said session.

NOTES

       If your OS doesn't support flock, you should understand the risks of going without locking the session files. Since sessions tend to be
       used in environments where race conditions may occur due to concurrent access of files by different processes, locking tends to be seen as
       a good and very necessary thing. If you still want to use this driver but don't want flock, set $CGI::Session::Driver::file::NoFlock to 1
       or pass "NoFlock => 1" and this driver will operate without locks.
