IIS Application Warm-up for IIS 7.5 improves the responsiveness of a web site by loading all related web applications and their dependencies before the first request is made.

IIS Application Warm-up improves the web site responsiveness even if it uses a custom request pipeline or if the Application Pool is recycled by “proactively loading and initializing all the dependencies such as database connections, compilation of ASP.NET code, and loading of modules.”

The pre-loading process, which can be executed synchronously or asynchronously, is initiated by configuring specific web pages and user IDs to be loaded and used.

Application Warm-up is integrated with IIS Manager and has the following main features:

  • Configuration settings are stored in the shared configuration file
  • Web application pre-loading settings can be configured on a per Web application basis, allowing IT professionals to identify or create individual initialization pages according to their needs.
  • Use the default or custom identities to pre-load the application.

This IIS module is currently in beta and has an x86 version for Windows 7 and an x64 one for Windows 7 or Windows Server 2008 R2.
