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 . REPLICATION Now Apache::Session::Memorycahed inclues replication between memecached servers Two new components provide a replication service . First package is Apache::Session::MemcachedReplicator Second is Apache::Session::MemcachedClient It's now possible to do replication master to slave or master to master see man pages and scripts . SOAP service Now Apache::Session::Memorycached inclues a SOAP service in order to set or get %session in any language . The SOAP service translates data in Perl hashes Installation of SOAP service All scripts are in scripts directory Put MemcachedSOAPClass.pm and MemcachedSOAP.cgi in the cgi-bin directory of your apache server with the appropriate right (x) . Change in MemcachedSOAP.cgi the memcached server address . (line 11 : $machine = 'ip.ip.ip.ip:11211'; ) Try the three scripts statTest.pl (first !) then getTest.pl finish with setTest.pl. The lemonldap project (SSO under GPL) uses this module AUTHOR This module was written by eric german . Completed by Habib ZITOUNI and Hamza AISSAT SOAP service is a contribution of Casimir ANTUNES .
