apc

I installed APC on my VPS and it works great with W3 Cache wordpress plugin. My problem is that there is one database in MySQL which is pinged by client end every few seconds to see if there are new updates. These db contains certain time sensitive information and hence it can't be part of cached data.

How can I disable APC for this database/files? or Can I set a very short expiry of certain type of data?

Any help is highly appreciated.
