I’m creating an app that uses Rails to serve webpages and node.js/socket.io to facilitate real-time communication. While Heroku can run node.js it can’t run websockets, thus I’m going to place the node.js app on linode and the rails app on Heroku.
My question:
In terms of DNS and cross domain issues how would I do this? For instance can I create an A Name record that points ‘domainname.com/websockets’ => linode and ‘domainname.com’ => heroku?
The WebSockets security model is not based on same-origin policy. This means that you should not have any cross-origin issues when using WebSockets.
