Session.quit versus ShowURL

If instead of Session.Quit I use: ShowURL(“”), the browser shows this page, but is the web session finshed too ?
If I include A Session.Quit after the ShowURL(“”) the typical screen when quiting appears as a flash and I dont want that.

The session will eventually die off. By default it’s 180 seconds (3 minutes) later. This is so the user can say “oops” and click the back button if they want to.
