intraweb forms doesn't have OnClose, because they are not auto-created and stay in the ram like in a vcl app.

i think the closest is to look at it like an MDI app (all the app is in one form and you create and destroy your \sub-forms\ as needed).

depending on your case, you can use the OnDestroy, use a global var, add yourself your own Notify event, or maybe even work with TIWMonitor.

If you want to detect onclose on the browser window you can register an event and intercept it so that it will send a callback to your app

And timeout the session

There is no sync way to detect when someone closes the browser window

This is why anyway you should count on the session timeout
