In the Global asax you can handle a InProc Session end event:

void Session_End(Object sender, EventArgs E) 
{     
    // do something 
}

A few reasons an InProc Session will died:

• Your IIS Application Pool has died, reset or etc.
• ASP.NET Worker Process (Aspnet_wp.exe) is recycled unexpectedly, overriding your bin or web.config

If an event occurs that causes the Application Pool to be recycled then InProc session will be lost. If the application is servicing a request, then I don't believe that the session associated with that request is lost, at least not until the response is served anyway.
