Thanks to @shanselman, we now have several tweaks to improve Azure experience.

On my Digital Ocean server I have NGINX proxying to Node and needed to add a some settings to the config to get sockets to work. Before I did that there was a little bit of a lag waiting on failover

This is what I added to my location block:

    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";

We should test this with Heroku too, I'll try later today or tonight if no one beats me too it

Working on Heroku with no changes, think this will be ok for everyone

@jasoncalabrese Yes, that's an Nginx detail. Socket.io simply falls back in ordinary situations. Glad it works.
