node.js with express routing to a new page within socket.io

I have a button on a page that when it is clicked, i want the page to call some node.js server code. I have this wired up via socket.io. The issue I am running into is I need the socket.io code to redirect my web page based on some business logic. Not sure what is the best way to do that via express (res.redirect?) and also how to get access to that within the socket.io call. Any help would be appreciated!

App.js

var dashboard = require('./middleware/dashboard.js');
...
app.get("/dashboard", function (req, res) {
    dashboard.show(req, res);
});
...
var http = require('http');
var server = http.createServer(app);
var io = require('socket.io').listen(server);

io.set('log level',2); // sets socket io log level 0=error, 1=warn, 2=info, 3=debug
...
dashboard.wireUpSocketIO(io);
...

dashboard.js

var savedResponse;

exports.show = function(req, res) {
    savedResponse = res;
    res.render("dashboard.jade"});
};


exports.wireUpSocketIO = function(io){
    io.sockets.on('connection', function (socket) {
        socket.on('dashboardOnButtonClick', function(msg) {

            <biz logic>

             savedResponse.render("someOtherPage.jade", {
                    locals: {
                        title: "someOtherPage",
                        filter: msg.filter
                    }
             });
        });
    });
}

dashboard.jade

button#btnFilter(class='btn btn-info') Test Button

script(src="/socket.io/socket.io.js")
script .
  var socket = io.connect('http://localhost');
  var emitMessage = { blah: false, filter:"n/a"};

  $('#btnFilter').click(function(){
      emitMessage.blah = true;
      emitMessage.filter = "filterByBlah";
      socket.emit('dashboardOnButtonClick', emitMessage);
  });
