That's how it works here, and how most forums probably work. However, if you have JavaScript enabled in your web browser (which most people do), there's nothing stopping a developer from putting code on the page which takes whatever you are typing and sending it to a server in the background. You can even code it to do it on every single keystroke if you wanted, so there would be a constant stream of data being sent as you type or delete characters. Of course, the main reason most sites don't do this is likely the pointlessness of it combined with the amount of data the server would have to process.
