On active Web sites, such as this one and some I built for clients, the site is always responding immediately as there is always something hitting the server. But, on development server, on all those I have been working with so far, I see that IIS goes down if no more hit is arriving. So, basically, it takes longer to start again on the next hit, if no hit has been hitting the server for several minutes. HTTP Keep Alive is checked. But, I have the situation. So, I am trying to figure out where is that setting that will make IIS always respond fast even if no hit has been happening in the last hour?
