as far as I have got much help on this forum I will aks again my newest question.
In my new plugin I am programming a form in four steps. After the lat step evrything is finished and the user must not go back to the form. Everything is OK with the back-button on the site, but not with the back button of the browser.
So first I have to detect when the browser-back button is clicked and in this case either to enable this button or redirect to another page.
How can I test the Broser-buttons?
