This is a RIAK based redirector for SQUID. The idea is following: Riak stores blocked resource's URL in a specified bucket (ie,'blocked'). Redirector program checks url against blocked resource by requesting appropriate key from riak. If key exists, then program redirects user to 'redrect_url' page.

-- Added: it is possible per fqdn redirection, i.e, to redirect from site1 to site2, just create a key 'site1' with text value 'site2', otherwise , if key exists without value, client will be redirected to 'redirect_url'

  curl -v -d 'http://site2.org'; -H "Content-Type: text/plain" http://<ip>:8098/buckets/blocked/keys/www.site1.org
