Subject: [SOLVED] But how then does a transparent proxy works?

I've found some hints

http://tldp.org/HOWTO/TransparentProxy-4.html:
>The reason is that the mechanism by which the process determines the
>original destination address has changed from linux 2.2, and only
>squid-2.4 has this new code in it. (For those of you who are interested,
>previously the getsockname() call was hacked to provide the original
>destination address, but now the call is getsockopt() with a level of
>SOL_IP and an option of SO_ORIGINAL_DST). 

http://wiki.squid-cache.org/SquidFaq/InterceptionProxy:
>You can usually manually configure browsers to connect to the IP address
>and port which you have specified as intercepted. The only drawback is
>that there will be a very slight (and probably unnoticeable) performance
>hit as a syscall done to see if the connection is intercepted. If no
>interception state is found it is processed just like a normal
>connection.

Thanks for your patience
