推荐答案

请勿在客户端计算机上执行此操作。



普遍接受的做法是在网络上设置代理服务器。



配置所有客户端使用代理服务器，因此他们的http请求被发送到代理服务器。



然后，在代理服务器上，您可以为允许的内容和不允许的内容设置规则。 br />


如果代理允许，它会将请求转发到互联网，当收到回复时，将其转发给客户。



显然，你需要锁定对于客户来说，代理设置无法更改。



市场上也有很多基于硬件的过滤设备。



请记住，客户端计算机不值得信任。将过滤逻辑放在网络级别更安全。



如果你想查看代码是如何工作的，有一个名为SQUID的开源系统可以做到这一点。但要注意，这是一个庞大而复杂的软件。

Do not do it on the client machine.

The generally accepted way of doing his is to set up a proxy server on the network.

Configure all clients to use the proxy server, so their http requests are sent to the proxy server.

Then, on the proxy server, you can set rules for what is allowed and what isn't.

If the proxy allows it, it will forward the request to the internet, and when it receives a response, forward that to the client.

Obviously, you need to lock down the clients, so that the proxy settings cannot be changed.

Their are loads of hardware based filtering devices in the market too.

Remember, that client machines are not to be trusted. Putting the filtering logic in at a network level is much more secure.

There is an open source system called SQUID that does this, if you want to look at the code for how it works. Beware, though, that this is large and complex software.
