detect when an app domain is being shut down

[Bubba]

Hi,

We have HttpHandlers that can process requests for up to 50 minutes. Those
HttpHandlers are running in an app domain inside the DefaultAppPool. We'd
like the HttpHandlers to be able to detect when its containing app pool or
app domain is requesting a shutdown (when it is recycling, for example). I
looked at the Application_End method in global.asax, as well as the System.
AppDomain.CurrentDomain.DomainUnload event. Neither get called as long as
the HttpHandlers are handling a client request. Is there a way to
programatically know when an app domain is about to shut down? We need to
know so that we can force the request to end more quickly and gracefully.

Thanks for you help.

Hi,
I think this can be handled inside AppDomain.UnhandledException event.
If you want complete working code for it then please let me know.

Thanks and Regards,

Hi,
Have you also tried AppDomain.ProcessExit?

Hi Manish,

Thanks for your input, but AppDomain.ProcessExit is not called while there
are requests running. Also, AppDomain.UnHandledException is not appropriate
because there are no exceptions thrown in this case.

Thanks,
Bubba

Since your http handlers are still executing you AppDomain will not shut
down so could you hook into any shutdown event?

In essence, that is what I want to do - but I don't know where to do that.
