Back in January my colleague Mai-lan blogged about IIS 7.5 new features. One of them is the long-awaiting warm up feature for some users, as he wrote,

Support for application pool warm-up for large applications that want to "prime" an application pool for better performance on the initial request.

Many guys, including me, were wondering where is it in Windows 7 7000. I could not find it as in IIS Manager there is no place to configure that. smile_confused

It is today that I finally come across the ASP.NET 4.0 whitepaper here, which reveals the sample configuration. I couldn’t help trying them out and WOW it works as expected! smile_teeth

The only limitation is that any change must be made to applicationHost.config file directly. This is normal as it is always not easy to have everything that visual.

As Visual Studio 2010 Beta 1 and .NET Framework 4.0 Beta 1 is around the corner, we can finally put our fingers onto the bits. Cool!smile_wink

Now Scott has a better post here and we have an IIS.net article covering all details,
