I'm working on a re-design of my companies web site. I need help in finding a reliable script that will password protect my clients web site prototype files on my server and allow them to login and check the status of their web projects. I've tried using my web hosts' password protection service but, 1) it works the first time you login, but if you try it again after that, the password login window doesn't popup and your let right into the so called "protected" file(s). And 2)It doesn't allow for customization of a login page or a failed login page that fits the look of your site. Someone please help me. Thanks in advance.
p.s. I don't have a lot of .......well let's be honest, I don't have ANY real programming ability. So please make your answer REALLY SIMPLE and EASY TO UNDERSTAND for a non-programmer. Thank you.
