Short Answer

If you want to access the "req/res" in the EJS templates, you can either pass the req/res object to the res.render() in your controller function (the middleware specific for this request):

res.render(viewName, { req : req, res : res /* other models */};

Or set the res.locals in some middleware serving all the requests (including this one):

res.locals.req = req;
res.locals.res = res;

Then you will be able to access the "req/res" in EJS:

<% res.redirect("http://www.stackoverflow.com"); %>

Further Discussion

However, do you really want to use res in the view template to redirect?

If the event initiates some request to the server side, it should go through the controller before the view. So you must be able to detect the condition and send redirect within the controller.

If the event only occurs at client side (browser side) without sending request to server, the redirect can be done by the client side javascript:

window.location = "http://www.stackoverflow.com";
