# CGI::Session::ID::incr(3pm)

CGI::Session ID driver

## 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`.
