Jquery AJAX (json) cross domain request and ASP.NET MVC
You can initiate cross-domain request in your webpage by creating either XMLHttpRequest object or XDomainRequest object. End user's web-browser will request data from the domain's server by sending an "Origin" header with the value of origin. If server responds with an "Access-Control-Allow-Origin: * | Origin" then we are permitted to access data; otherwise response will be unauthorized request.
protected void Application_BeginRequest(object sender, EventArgs e)
{
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
// HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "http://AllowedDomain.com");
}

Seemed to me to be a beaten theme, but i couldn't find the answer. =( I make jquery ajax requst to localhost:666 from localhost:555 application
$.ajax({ url: "http://localhost:666/request", dataType: 'json', timeout: 5000, success:...
i've got in chrome:
XMLHttpRequest cannot load http://localhost:666/request. Origin http://localhost:555 is not allowed by Access-Control-Allow-Origin.
What is the solution of the problem?
