Question

We are using Nhibernate and second level cache (non strict read write). When profiling the app using NH Profiler, I can see that data are requested once. But if the web app is idle, after a few minutes, at first request, data are requested again… Is there some expiration date/timeout on the cache? What should I do to prevent the cache from being cleared?

Assuming you’re using SysCache :

<configuration>
  <configSections>
    <section name="syscache" type="NHibernate.Caches.SysCache.SysCacheSectionHandler,NHibernate.Caches.SysCache" />
  </configSections>

  <syscache>
    <cache region="foo" expiration="500" priority="4" />
    <cache region="bar" expiration="300" priority="3" />
  </syscache>
</configuration>
