IHTMLXDomainRequest interface

Implements cross-domain Asynchronous JavaScript and XML (AJAX) requests between the browser and a server.

Members

The IHTMLXDomainRequest interface inherits from the IDispatch interface but does not have additional members.

Remarks

Cross-domain requests require mutual consent between the Web page and the server. You can initiate a cross-domain request by creating an XDomainRequest (XDR) object with the window object, and opening a connection to a URL. When sending the request, Windows Internet Explorer 8 includes an XDomainRequest: 1 HTTP request header. The connection is completed only if the server responds with an XDomainRequestAllowed: 1 response header.

To use the XDR protocol, you first create an XDomainRequest object. Then you use the IHTMLXDomainRequest::open method to establish a connection with a server. Once a connection is opened, the IHTMLXDomainRequest::send method transmits data strings to the server for processing. For example:

  
// 1. Create XDR object 
xdr = new XDomainRequest(); 

// 2. Open connection with server using POST method
xdr.open("POST", "http://www.contoso.com/xdr.txt");

// 3. Send string data to server
xdr.send("data to be processed");     
                

For more information, see XDomainRequest.
