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


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


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:

    $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 one above.


The only optional argument for file is Directory, 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.
