Application-scoped COM object -> Is there a way to determine when IIS is shutting down? -- inetserver asp components

I want the COM component to hook into some sort of shutdown event, so I can
flush logs and stuff when IIS is shutdown, either by IISReset, "net stop
iisadmin", or the OS shutting down.

It appears that Application-scoped COM objects don't get an OnEndPage method
called when IIS is stopping - should they?

It's possible that I could hook into either IUnknown.Release(), or
DllMain(DLL_PROCESS_DETACH). However, the component is written in C# and
I'm using COM Interop, so it's pretty hairy to hook into the
IUnknown.Release(), and that may occur too late? And I can't hook into
PROCESS_DETACH with managed code, so I'd have to write another DLL in C++
and load it. Either of these approaches are doable but kinda hairy.

Is there an easier approach that anyone's aware of?

Thanks in advance,

Use the Application_onEnd event in the global.asa file
