libgdx's http request method doesn't work on the web application

Question

I'm testing the net class of libgdx library to get a json from the page passed to the setUrl method. This portion of code comes from a class called ApplicationScreen that implements the libgdx Screen interface. That's the code:

@Override
public void show() {

    String requestContent = null;

    httpRequest = new HttpRequest(Net.HttpMethods.GET);
    httpRequest.setUrl("http://localhost/projects/SqlParser/index.php");
    httpRequest.setHeader("Content-Type", "text/plain");
    httpRequest.setContent(requestContent);

    Gdx.net.sendHttpRequest(httpRequest, new HttpResponseListener() {

        public void handleHttpResponse(HttpResponse httpResponse) {

            final int statusCode = httpResponse.getStatus().getStatusCode();

            System.out.println("HTTP Request status: " + statusCode);
            System.out.println("Content:");
            System.out.println(httpResponse.getResultAsString());


        }

        public void failed(Throwable t) {
            System.out.println("HTTP request failed!");
        }

    });

}

When I run the desktop version I get this message on the Console window "HTTP Request Status: 200", followed by the content of the http request, so the code does what I expect it should do. When I run instead the html version I get this message on the Console "HTTP Request status: 0". Any suggestion?

I solved the problem using an unsecured version of Google Chrome, launching the browser with these options: --allow-file-access-from-files --disable-web-security
