http {
map $arg_option $step2 {
default 1;
com_hwdmediashare $arg_task;
}

map $step2 $step3 {
default 1;
addmedia.upload $request;
}

map $step3 $blocked {
default 1;
~*(?:\?|&)?base64encryptedstring 0;
}

server {
location / {
return 404;
}

location /index.php {
if ($blocked) {
return 404;
}
}

location /media/com_hwdmediashare/assets/swf/Swiff.Uploader.swf {
}
}
}
