Execute Task when AppPool is recycled

[jdemmi]

Any ideas for this one???

W2K3 .Net 1.1 app.

We have IIS configured to recycle the app pool when the virtual memory reaches a certain threshold.

This is an OOB IIS option and is handy for cleaning up the LOH.

Now....here's my dilemma.

I have a "dependent service" when needs to be recycled any and every time the app pool is recycled.

For now I am handling this manually but I would love to find a way to automate it....any suggestions?

use either the ApplicationBegin or ApplicationEnd to handle starting/stopping global services to the site.

Can you elaborte?

Keep in mind that the recycling event is managed internal by Microsoft (IIS) (not my app).

the root object to the asp.net pipeline is HttpApplication. when you add a global.asax file the code behind reads

public class Gloabl : HttpApplication 
{ 
}

from this object you can hook into a variety of points in the pipeline. Application_Start executes the first time the website is accessed no users to 1 user. Application_End executes as the application is shutting down. this can be when the app pool is recycled. after the last user has been inactive for a period of time, etc.

so when the application starts, start the service, and when the application ends, stop the service. I forget the exact objects to use but it's something like

Process p = new Process("[commands to start service]");
p.Start();
p.WaitOne();

Process p = new Process("[commands to stop service]");
p.Start();
p.WaitOne();
