Prevent IIS from flushing cache

I'm trying to get IIS not to flush cached data, so that the loading of the pages after a period without requests can be faster. SO far I've tried this, but with any success:

• define an infinite time for the "Object Cache TTL" property;
• unchecked on IIS (version 6.0) the option "Recycle worker processes";
• unchecked on IIS the option "Shutdown worker processes after 开发者_Python百科being idle..";
• set cache ActivityPeriod as "0".

What could I be missing? Is there something that is forcing cache to be flushed after some time idle?

If you are using ASP.NET, you can control caching with web.config settings or programatically.
