    print "start";
    foreach $links (@links) {
        if($links=~m/^\// and $_=~m/\/$/) {
            substr($links, 0, 1) = undef;
            print "1";

that array idea sounds good, but how musch memory would that take up? Does anyone know how i could do it using files? Obviously this isnt going to be a huge webcrawling expedition, but it could end up with 100,000 sites in its array if it hits a very linkish site a couple times. Thanks
