I have problem with my simple NodeJS app. I am using connect with express-session module.

module.exports.logout = function (request, response, next) {
if (request.session.user) {
    request.session.destroy(function (error) {
        next(error);
    });
}
response.writeHead(301, 'Please login', { 'Location': 'login' });
response.end();
};

The problem is logout page. Whan I run app and firstly logout user i works fine, but when I login second time and logout it only redirect to login page without logout user. I think the problem is because browser use cache for redirects. How to force it?

You need to wait for `destroy()` to finish. – SLaks Aug 28 '16 at 15:46
But when I create header in callback function I get error "headers already send". Could you show short code how to properly code it? – Mati Aug 28 '16 at 15:52
You need to only send a response once, not twice. – SLaks Aug 28 '16 at 16:03

If the page should not be cached make sure it has these minimum set of HTTP headers: http://stackoverflow.com/questions/49547/making-sure-a-web-page-is-not-cached-across-all-browsers – slebetman Aug 29 '16 at 07:09
This did the trick! Thanks! – Mati Aug 29 '16 at 08:58
