GlobalCache: Multi-Server Support for APC and xCache

1 Requirements

The current implementation of GlobalCache in ILIAS 5.0 doesn't support a multi-server environment with APC. In ILIAS 5.1 you can use Memcached for multi-server environments. This feature requests adds the functionality of multi-server-flushing on APC and xCache.

The caching-service stores a token in the client.ini-File and in the cache itself. When a flush is triggered, a new token is stored in client.ini. ilGlobalCache comperes the stored in cache value with the value in client.ini. If those doesn't match, the cache is flushed and the new token is stored in cache.
