When a CInternetServer object goes out of scope, the
destructor is automatically called to allow the library to free any
resources allocated on behalf of the process. Any pending blocking or
asynchronous calls in this process are canceled without posting any
notification messages, and all handles that were created for the
connection are destroyed. If there are any clients connected to the
server at the time the destructor is called, those client sessions
will be immediately terminated.
The destructor is not called explicitly by the application.
