I'm new to programming. I'm trying to stop someone from going to my website. I can't use shtml extensions or any of the following (ASP,Cold Fusion, PHP, Perl,CGI etc..)  to block an ip addresses. I picked the wrong hosting provider.  I was told I could post a question in the java area and ask someone if they could build and compile a java applet that takes two input parameters: 1 a comma delimited list of ips you want to block and a field for what page you want them sent to. The static IP address is I would like to send this ip address to an unknown web page. As if the site is down. Can this be done?  Thanks

Whatever program you use, what's to stop them simply opening their browser and going to whereever they want?

So You need a Java applet You insert Your starting page, and If the ip of request is in Your blocking list (first parameter of applet), You forwarded another site, else access granted to Your site (second parameter)?

It is easy to code this Applet, but there is a huge problem with maintanance. As is understand You question, You can't use dinamic contents. So that You have static HTML site. You cant deny somebody had access before to Your page, even You modify Your web local URLs. If they have already reach Your authorized area, they have the URL, that escape the authorization. So that You have to change this URL even You changed the denied IPs.

Think about that, and If You need help, I will weekend!

That technique can be easily bypassed by just disabling Java on the browser.
