IIS: web applications warmup

After IIS reset, first hit taking a long time because AppPool is starting and other .NET components, DB connections are initializing.

What would be the best way to warm up IIS applications and preload required components (e.g. GAC Assemblies, WCF, WWF libraries)

I'm working on IIS 6, Windows 2003 server x64

(I know there is warmup module for IIS 7, but I'm on IIS 6.how that warmup module in IIS 7 works internally?)

Some tips on warm up scripts:
