I have an adult content website done in iWeb on a mac. The homepage is a warning page that has 'enter' or 'leave' with a warning on it. So far so good, but, all the pages are coming up in Google and if a user clicks on any page other than the homepage they bypass the warning page. So I need some sort of session script that will re-direct the user to the home page if they access a page from an outside source and then once through that they can browse any of the pages in the site. They don't need to verify their age, I just need them to be able to read the warning.
