Using Redis to Keep Track of Page Views from Incoming Traffic

I'm trying to use Redis to keep track of page views so I can figure out which pages get the most views from incoming traffic (rather than from browsing within the site). However, right now when I check the quote ID in Redis, the value being returned is nil. I've added both to routes.rb. Thanks!

Here's the Javascript I'm using:

    function viewCount(quote_id) {        $.ajax({            type:"PUT",            url:"/quotes/" + quote_id +"/viewed",            contentType:"json"        });    }    function quoteReferrer(quote_id){        if ((document.referrer != null) && (location.hostname !=(document.referrer.split('/')[2])))        {            $.ajax({                type:"PUT",                url:"/quotes/" + quote_id +"/referred",                contentType:"json"            })        }    }

The Ruby controller code:

      def viewed        REDIS.incr("quote_id_#{params[:id]}_viewed_count")        puts params[:id]        respond_to do |format|          format.json { head :ok }        end      end      def referred        REDIS.incr("quote_id_#{params[:id]}_referred")        puts params[:id]        respond_to do |format|          format.json { head :ok }        end      end
