| // jsonp is a handy technique for getting around the limitations of the same-origin policy. |
| // (http://en.wikipedia.org/wiki/Same_origin_policy) |
| // |
| // normally, to dynamically update a page you use an XmlHttpRequest. this has flakey support |
| // is some browsers and is restricted by the same origin policy. you cannot perform XHR requests to |
| // someone else's server. one way around this would be to proxy requests to all the servers you want |
| // to xhr to, and your core server - so that everything has the same port and host. |
| // |
| // another way, is to turn json into javascript. (which is exempt from the same origin policy) |
| // this is done by wrapping the json object in a function call, and then including a script tag. |
| // |
| // here we're proxing our own JSON returning server, but we could proxy any server on the internet, |
| // and our client side app would be slurping down JSONP from anywhere. |
| // |
| // curl localhost:1337/whatever?callback=alert |
| // alert([]) //which is valid javascript! |
| // |
| // also see http://en.wikipedia.org/wiki/JSONP#JSONP |
