Apache::Session::SharedMem - Session management via shared memory
use Apache::Session::SharedMem; tie %s, 'Apache::Session::SharedMem', $sessionid, { expires_in => 86400 }
This module is an implementation of Apache::Session. It uses IPC::Cache to store session variables in shared memory.
The advantage of this is that it is fairly fast (about the same speed, if not faster than Apache::Session::File and is very easy to set up making it perfect for when you want to test sessions but can't be bothered to set up a database or don't want cgi scripts writing temp files.
It probably isn't very scaleable (i.e you probably shouldn't use this in production code which is going to get hit hard.
I have no idea if it leaks memory yet. I've only just written it :)
Apparently it IPC::ShareLite (and hence IPC::Cache) don't work under Perl 5.6.
Just the same as all the other Apache::Session modules. You can optionally pass the parameter expires_in which will tell the Session to expire in a certain time.
Apache::Session::SharedMem needs Apache::Session and IPC:Cache, both available from the CPAN.
