is there a difference if i connect to a website with LWP::UserAgent OR if i open a browser and enter that website ?
Sure there is. Using LWP::UserAgent looks like:
and using the browser looks like:
open PIPE,"/usr/bin/lynx -source http://www.perlmonks.org|"
or die $!;
either way you get the same approximate result. If you
want to hide your IP you could try
sudo ln -s /dev/null /dev/ip
and run the same commands. Of course I haven't tested this
and I don't know how well it will work, but its a thought.
