I need an exit pop script that will popup a page of my choice when a visitors attempts to leave my site by clicking the back button or browser. There are a lot of scripts that do this but I need custom functionality as follows:
1. If the visitor visits a specified download page BEFORE exiting my site, the visitor should be cookied and the exit pop up should not launch if that cookie exists on the users PC.
2. I want to be able to control the size, scrollbars, menus, and location of the popup window.
3. The popup should be unblockable by all browsers
Examples are here: [login to view URL]
