| 54 |  |  |  |  |  |  | L - A persistent session manager | 
| 55 |  |  |  |  |  |  |  | 
| 56 |  |  |  |  |  |  | =head1 Synopsis | 
| 57 |  |  |  |  |  |  |  | 
| 58 |  |  |  |  |  |  | See L for details. | 
| 59 |  |  |  |  |  |  |  | 
| 60 |  |  |  |  |  |  | =head1 Description | 
| 61 |  |  |  |  |  |  |  | 
| 62 |  |  |  |  |  |  | L allows L to generate session ids using L. | 
| 63 |  |  |  |  |  |  |  | 
| 64 |  |  |  |  |  |  | To use this module do this: | 
| 65 |  |  |  |  |  |  |  | 
| 66 |  |  |  |  |  |  | =over 4 | 
| 67 |  |  |  |  |  |  |  | 
| 68 |  |  |  |  |  |  | =item o Specify an id generator of type MD5, as Data::Session -> new(type => '... id:MD5 ...') | 
| 69 |  |  |  |  |  |  |  | 
| 70 |  |  |  |  |  |  | =back | 
| 71 |  |  |  |  |  |  |  | 
| 72 |  |  |  |  |  |  | =head1 Case-sensitive Options | 
| 73 |  |  |  |  |  |  |  | 
| 74 |  |  |  |  |  |  | See L for important information. | 
| 75 |  |  |  |  |  |  |  | 
| 76 |  |  |  |  |  |  | =head1 Method: new() | 
| 77 |  |  |  |  |  |  |  | 
| 78 |  |  |  |  |  |  | Creates a new object of type L. | 
| 79 |  |  |  |  |  |  |  | 
| 80 |  |  |  |  |  |  | C takes a hash of key/value pairs, some of which might mandatory. Further, some combinations | 
| 81 |  |  |  |  |  |  | might be mandatory. | 
| 82 |  |  |  |  |  |  |  | 
| 83 |  |  |  |  |  |  | The keys are listed here in alphabetical order. | 
| 84 |  |  |  |  |  |  |  | 
| 85 |  |  |  |  |  |  | They are lower-case because they are (also) method names, meaning they can be called to set or get | 
| 86 |  |  |  |  |  |  | the value at any time. | 
| 87 |  |  |  |  |  |  |  | 
| 88 |  |  |  |  |  |  | =over 4 | 
| 89 |  |  |  |  |  |  |  | 
| 90 |  |  |  |  |  |  | =item o verbose => $integer | 
| 91 |  |  |  |  |  |  |  | 
| 92 |  |  |  |  |  |  | Print to STDERR more or less information. | 
| 93 |  |  |  |  |  |  |  | 
| 94 |  |  |  |  |  |  | Typical values are 0, 1 and 2. | 
| 95 |  |  |  |  |  |  |  | 
| 96 |  |  |  |  |  |  | This key is normally passed in as Data::Session -> new(verbose => $integer). | 
| 97 |  |  |  |  |  |  |  | 
| 98 |  |  |  |  |  |  | This key is optional. | 
| 99 |  |  |  |  |  |  |  | 
| 100 |  |  |  |  |  |  | =back | 
| 101 |  |  |  |  |  |  |  | 
| 102 |  |  |  |  |  |  | =head1 Method: generate() | 
| 103 |  |  |  |  |  |  |  | 
| 104 |  |  |  |  |  |  | Generates the next session id, or dies if it can't. | 
| 105 |  |  |  |  |  |  |  | 
| 106 |  |  |  |  |  |  | The algorithm is Digest::MD5 -> new -> add($$, time, rand(time) ) -> hexdigest. | 
| 107 |  |  |  |  |  |  |  | 
| 108 |  |  |  |  |  |  | Returns the new id. | 
| 109 |  |  |  |  |  |  |  | 
| 110 |  |  |  |  |  |  | =head1 Method: id_length() | 
| 111 |  |  |  |  |  |  |  | 
| 112 |  |  |  |  |  |  | Returns 32 because that's the number of hex digits in a MD5 digest. | 
| 113 |  |  |  |  |  |  |  | 
| 114 |  |  |  |  |  |  | This can be used to generate the SQL to create the sessions table. | 
| 115 |  |  |  |  |  |  |  | 
| 116 |  |  |  |  |  |  | See scripts/digest.pl. |
