Sample code:

    // Universal request method. You can use HttpRequestOptions to set varios properties, 
    // HttpHeader to get/set desired headers, HttpResponse to get status code, headers 
    // and content and HttpContent to get body of response:

    interface HttpRequestOptions {
        url: string;
        method: string;
        headers?: HttpHeader[];
        content?: HttpContent;

    }

    interface HttpResponse {
        statusCode: number;
        headers: HttpHeader[];
        content?: HttpContent;
    }

        toString: () => string;
        toJSON: () => any;
        toImage: () => image_module.Image;
    }

    // Get request

    }).then(function (r) {
        var status = r.statusCode;

        for (var i = 0, l = r.headers.length; i < l; i++) {
            var header = r.headers[i];
        }

        var result = r.content.toJSON();

    }).fail(function (e) { });

    // Post request
    http.request({

    }).fail(function (e) { log(e) });

    }).fail(function(e) { console.log("Error:" + e.message); });
                                                      
    http.getJSON("http://www.reddit.com/r/aww.json?limit=10").then(function(result) {
           // Result is JSON!  
    }).fail(function(e) { console.log("Error:" + e.message); });

    http.getImage("http://www.google.com/images/errors/logo_sm_2.png").then(function(result) {
