This brings up something I do not understand. Take a single use exe com server in a pool for the web. It's protected from any other hit? For instance a cReturnHTML property is safe cause the server is single use? But you can have 2 or more instances going. What about a multithreaded dll com server doing the same, say with ASP? Its init and destroy are initialized with each request but a property like cReturnHTML can be trampled? I'm trying to picture what is instantiated and what is separated or shared and don't get it. Thanks
