What existing plugin do :
Plugin show exit popup (standard browser exit dialog) always when visitor want to close page or want to go on other domain ([url removed, login to view])
What I need to add :
I need to add a control of some domains which will be excluded from popup. It means that i will write somewhere that [url removed, login to view] is excluded and popup will not show if visitor go from sit to [url removed, login to view] but will show at all other domains + web close.
