Apc_store does not work between requests

$bar = 'BAR'; apc_store('foo', $bar); var_dump(apc_fetch('foo'));

Within the framework of one request this work.

Now, if I try to execute var_dump(apc_fetch('foo')); on another request, it prints:

 bool(false)

Any help?

I'm on gentoo with PHP 5.2, APC-3.1.9

Here is what phpinfo () knows about APC:

If you need other information, please tell me.

Here is how I installed it: https://serverfault.com/questions/274261/failed-installing-apc

I noticed one thing: in the phpinfo Configure command, I did not find apc

Maybe you are using PHP on top of CGI (instead of FastCGI, which you should use) - see my answer in another question why APC does not work if PHP is working on CGI.

By default, ttl (apc.ttl) is 0 seconds, this is strange - try specifying ttl (in seconds) while saving the value:

 apc_store('foo', $bar, 60);
