All I want is what the explorer user prompt is but web site base so it can be added to my sitre as a search engine this password protect works like this.. what ever the webpage is that is the password. Build a page called hello and then typing in hello as the pasword thats what I want but with out the prompt so it can be embeded in to a html page. What I am tring to do is turn it into a search engine I know how to do the rest of it ust not this part. I am not a java programer but a html programer (Removed by Admin for Violation of Terms of Service)
