Keep user caches despite Application Pool recycling

I'm desperatly trying to find a way to prevent my usercaches from being deleted upon App Pool recycling. 

I'm currently on a Windows 2008 Server with IIS as web server, and want to use win cache as a long term cache for specific MySQL-results. I have my own handlers to invalidate those caches, and pretty much just want to keep these until the app triggers the invalidation. 

On my development machine I'm running a LAMP-stack and with APC there's simply not that problem at all. Is there any way I can replicate this behavior with IIS? 

If I'm not completely mistaken there's a default recycling of idle pools which I can adjust, but there's still the matter of "global" recycling of pools every 24th hour or so.

Any suggestions?
