I want to write a program to filter web content. I believe that i can write a filter program by usig java however problem is that how can i place this program like "internet -> filter -> web browser" ?

Does anybody have any idea ?

Thanks

Isn't it just a matter of making it work like a proxy server? That's how filters like DansGuardian work.

yes it can work like proxy server. I have already written a simple proxy server. It can only connect google port 80 for now. In local I gave port 3398 to this proxy server. I configure firefox proxy server setting like "localhost, port 3398" and it is working correctly. My plan is that i want to configure network setting to all my web browser (firefox, opera, konqueror etc.) use my proxy server. I have tried to configure iptables to do that but i couldn't.

Thank you for reply

Could you post the iptables commands you've tried? Someone may be able to spot where you went wrong.

You may want to try OpenDNS (opendns.org). Set your routers to use it (which speeds up Internet traffic to boot) and then enable content filters. You can block sites by category or make custom rules. Might be easier than making an app from scratch.
