## NAME
    [CGI::Session::ID::incr] - [CGI::Session] ID driver

## SYNOPSIS
        use [CGI::Session];
        $session = [CGI::Session]->new("id:Incr", undef, {
                                    Directory   => '/tmp',
                                    IDFile      => '/tmp/cgisession.id',
                                    IDInit      => 1000,
                                    IDIncr      => 2 });

## DESCRIPTION
    [CGI::Session::ID::incr] is to generate auto incrementing Session IDs.
    Compare it with [CGI::Session::ID::md5], where session ids are truly
    random 32 character long strings. [CGI::Session::ID::incr] expects the
    following arguments passed to [CGI::Session]->new() as the third argument.

    IDFile
        Location where auto incremented IDs are stored. This attribute is
        required.

    IDInit
        Initial value of the ID if it's the first ID to be generated. For
        example, if you want the ID numbers to start with 1000 as opposed to
        0, that's where you should set your value. Default is 0.

    IDIncr
        How many digits each number should increment by. For example, if you
        want the first generated id to start with 1000, and each subsequent
        id to increment by 10, set *IDIncr* to 10 and *IDInit* to 1000.
        Default is 1.
