### This file implements a blacklist for certain user agents and
### referrers. It's a first line of defense. It must be included
### inside a http block.


## Add here all user agents that are to be blocked.
map $http_user_agent $bad_bot {
    default 0;
    ~*^Lynx 0; # Let Lynx go through
    libwww-perl                      1;
    ~(?i)(httrack|htmlparser|libwww) 1;
}

## Add here all referrers that are to blocked.
map $http_referer $bad_referer {
    default 0;
    ~(?i)(babes|click|diamond|forsale|girl|jewelry|love|nudit|organic|poker|porn|poweroversoftware|sex|teen|webcam|zippo|casino|replica) 1;
}

## Add here all hosts that should be spared any referrer checking.
geo $bad_referer {
    127.0.0.1 0;
    192.168.1.0/24 0;
}
