add support for redirecting to a fake xanga proxy on blocked ips - currently hardcoded to duckandchicken.net.  requires the following apache config to work:

[VirtualHost *:80]
        Servername www.xanga.com
        ServerAlias *.xanga.com xanga.com
        DocumentRoot /home/jaymz/test1
        ProxyPass / http://xanga.com/ connectiontimeout=30 timeout=60
        #ProxyPass / http://xanga.com/
        ProxyPreserveHost  On
[/VirtualHost]
