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
