The Superstatic AJAX proxy lets you make requests to other domians without violating the Same-Origin Policy. For instance, you could mount a proxy called api that pointed to https://api.your-app.com. Once you've done so, a request to e.g. /__/proxy/api/users.json would be proxied through to https://api.your-app.com/users.json.

The configuration for superstatic-proxy is an object where the keys are reference names for the service to which you're proxying and configuration details. An example (comments for clarity despite JSON syntax):

{"api": {// the origin of the server to which you want to make requests"origin": "https://api.your-app.com",// set default headers present on every request. these can be// overridden on individual AJAX requests"headers": {"Accept": "application/json"},// if true, send the cookies from the static app along to the server"cookies": false,// set a timeout for requests sent to the proxy (defaults to 30 seconds)"timeout": 30}}
