IXMLHttpRequest Interface

---

This interface provides client-side protocol support for communication with HTTP servers.

IXMLHttpRequest Methods

abort	Cancels the current HTTP request.
getAllResponseHeaders	Retrieves the values of all the HTTP headers.
getResponseHeader	Retrieves the value of an HTTP header from the response body.
onreadystatechange	Specifies the event handler to be invoked when the readyState property changes.
open	Initializes a Microsoft.XMLHTTP request, and specifies the method, URL, and authentication information for the request.
readyState	Represents the state of the request.
responseBody	Represents the response entity body as an array of unsigned bytes.
responseStream	Represents the response entity body as an IStream.
responseText	Represents the response entity body as a string.
responseXML	Represents the response entity body as parsed by the MSXML DOM parser.
send	Sends an HTTP request to the server and receives a response.
setRequestHeader	Specifies the name of an HTTP header.
status	Represents the HTTP status code returned by a request.
statusText	Represents the HTTP response line status.

Remarks

A client computer can use the XMLHttpRequest object (Microsoft.XMLHTTP) to send an arbitrary HTTP request, receive the response, and have the Microsoft XML Document Object Model (DOM) parse that response.

This object is integrated with MSXML to support sending the request body directly from, and parsing the response directly into, the MSXML Document Object Model objects. When combined with the support for XSL, the XMLHttpRequest component provides an easy way to send structured queries to HTTP servers and efficiently display the results with a variety of presentations.
