NAME

Apache::Session::Memorycached - An implementation of Apache::Session

SYNOPSIS

use Apache::Session::Memorycached;

   tie %session, 'Apache::Session::Memorycached', $cookie, {
         'servers' => ["10.75.1.19:11211"], #all write operations
         'local'  =>  ["localhost:11211"],  #read-only operations
         'timeout' => '300'
    };

tie %s, 'Apache::Session::Memorycached', undef,
   {servers  => ['mymemcachedserver:port'],
    'timeout' => '300',
    'updateOnly' => 1 ,
    'principal' => uid,  
       };

In order to optimize the network ,you can use a local memcached server. All read-only opération are sending fisrt at local server .If you need write ou rewrite data , the data is sending at the principal memcached sever and local cache too for synchronisation.

note : 'updateOnly' => 1 just realize up-date operation not init operation. Init operation is use in order to book and lock the number session but it's not available in this module

 'principal' => uid :  this  parameter is use to create reverse reference 
 like this : MD5_hex(uid) => id_session in memcached server . By this it usefull to retrieve id_session from principal name . And add uid_MD5 => MD5_hex(uid) in main session .

DESCRIPTION

This module is an implementation of Apache::Session. It uses the memcached system backing store . You may specify servers (principal) and locals caches for locking in arguments to the constructor. See the example, and the documentation for Apache::Session::Store::Memorycached and Cache::Memcached .

The lemonldap project (SSO under GPL) uses this module
