Overview:

Every time your site is requested ASP.NET needs the .NET Framework runtime to be loaded into memory in order to answer the request of your visitor. To save valueable resources IIS unloads this runtime if there is no request for some time. This is the reason why requests to your site need sometime 20-30 seconds until the Homepage ist displayed to your visitors.

There are some other programs (e.g. modules, workarounds) outside available - but we have seen none having the simplicity and stability of our real Windows Service.

It does it's task in the background and keeps your DNN sides online. Every request to to your sites is operated on a separate thread. To keep connection/bandwidth costs small the service should be (but must not) installed on the Webserver (IIS) running your IIS Sites. But you can also use it from any Internet connected Windows Client /w .NET Framework 2.0 installed. So DNN KeepAlive ist the perfect solution - even if your sites are hosted by an ISP.

Advantages:

• no interactive Login necessary - just tell the Service which Sites you like to keep alive - that's all
• minimal connection/bandwidth costs if installed on your IIS Webserver
• no DNN Programming Skills needed - runs out of the box
• no config files to edit, no file replacement or other complicated configuration needed
• the service is comfortable controlled and configured via the Windows SysTray and a special Controller Application
• each DNN Portal has it's own "Keep Alive Interval"
• each site is kept alive in a separate thread resulting in less memory usage and responsablitity of your system
• a daily E-Mail-Report informs you about the activity on your sites
• view current and previous activity with the Controller Application Charts
• New in the April 2008 Release: "Alert Me":
  If one of your sites is not accessible you can be informed by e-mail - just configure the number of "allowed" failed requests.

Summary:

ASP.NET frees resources after some idle time (in fact that's true for nearly every Homepage). So resources which are needed to show your IIS Homepage have to be loaded on each visit - and that's the reason for the startup delay.

DNN KeepAlive requests your portals at given intervals and effectively prevents ASP.NET from thinking your Site is not visited ;-)
