Password protect site/hide from search engines

Hi all,

I'm working on a webpage for my employer. It needs to be password protected, and invisible to search engines. I'm just wondering if there's some script that will accomplish this, as I'm rather noobish. I have managed in the past to cobble together a purchase history page with PHP and MySQL but that was a few years ago.

I can follow instructions, just don't know how to write scripts.

The username should be the same for all users.

I'd like to be able to set and modify a guest password (if someone at my work doesn't have their own email account, they can access the webpage but I can change the guest password each time someone leaves the company).

I'd like users to sign up via email verification - but only allow emails from a specific domain, like @myemployer.com

Would I need to use such a script on each page that I want protected?

Sorry if these are noob questions...

Search Engines honor the conditions in the Robots.txt file, you can use it to block specific user agents. So you can even block a specific search engine because each search engine has a user_agent string like 'YahooSpider'.

So to block all search engines:
Make a robots.txt file and put it in the root of the web server - e.g public_html. Then write this starting from the first line:


User-agent: *
Disallow: /



To password protect it, basic HTTP authentication (http://php.net/manual/en/features.http-auth.php) with sessions will do it.
