MrCarlito-0.1 is an experimental spider that collects header & link information from web pages. The spider is written in PERL (Practical Extraction and Report Language), and uses the LWP::UserAgent Class. Currently this spider does not delve into websites, it simply obtains the headers & hostnames contained in your web page index.
Humm you had better fix this broken bot if you plan on using it for a real website.
Your blocked because you were detected loading webpages not headers.
