Currently my wordpress blog (hosted on DO) is displayed at blog.mydomain.com and I am trying to display it on mydomain.com/blog. mydomain.com is an heroku application (node) so I set up a proxy using express-http-proxy with the following (on the heroku side):
app.use('/blog', proxy('blog.mydomain.com', {
forwardPath: function(req, res) {
return require('url').parse(req.url).path;
}
}));
ON DO’s side, I have changed the wordpress home url and site url in the wp-config.php like so:
define('WP_HOME','http://www.mydomain.com/blog');
define('WP_SITEURL','http://www.mydomain.com/blog');
My blog displays well on mydomain.com/blog but I can’t seem to login on the wordpress admin page (/wp-admin), I always get the error:
ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.
Of course my cookies are enabled and I tried different browsers . I am sure I am missing something but I can’t figure it out. Do you have any ideas?

It sounds like that the proxy could be dropping the cookies when passing on requests. express-http-proxy has a preserveHostHdr setting that will make sure the host HTTP headers are passed along. Doing some testing, this seems to work quite well:
var express = require('express');
var app = express();
var proxy = require('express-http-proxy');
app.get('/', function (req, res) {
res.send('Oh, hai!');
});
app.use('/blog', proxy('my.ip.addr', {
preserveHostHdr: true,
forwardPath: function(req, res) {
console.log('Proxying to ' + req.url)
return require('url').parse(req.url).path;
}
}));
app.listen(80, function () {
console.log('Listening on port 80!');
});
Using this, I am successfully able to login to the wp-admin panel.
