The recent discussion about how Google has attempted to control access to it's site has shown that this is really not as easy as it sounds.
IF one checks for the 'browser type', then the person using lwp will need to 'spoof' an acceptable $ua->agent($correct_type); prior to calling your web-site.
You could try the 'check to see if one can set a cookie' but that would be problematic, since again the coder with lwp could deal with that problem.
In essence you are trying to solve the turing test by establishing that the thing you are 'talking with' is actually a human and not an automaton.
