open Method (IXMLHTTPRequest)

Script Syntax

oXMLHttpRequest.open(bstrMethod, bstrUrl, varAsync, bstrUser, bstrPassword);

Parameters

bstrMethod

The HTTP method used to open the connection, such as GET, POST, PUT, or PROPFIND.

bstrUrl

The requested URL. This can be either an absolute URL, such as "http://Myserver/Mypath/Myfile.asp", or a relative URL, such as "../MyPath/MyFile.asp".

varAsync [optional]

A Boolean indicator of whether the call is asynchronous. The default is True (the call returns immediately). If set to True, attach an onreadystatechange property callback so that you can tell when the send call has completed.

bstrUser [optional]

The name of the user for authentication. If this parameter is Null ("") or missing and the site requires authentication, the component displays a logon window.

bstrPassword [optional]

The password for authentication. This parameter is ignored if the user parameter is Null ("") or missing.

Example

The following script example creates an XMLHTTP object, and then uses the open method to synchronously open an Active Server Pages (ASP) page. The script then posts an XML document to an ASP page, which uses the load method to load the document.

var xmlhttp = new ActiveXObject("Msxml2.XMLHTTP.5.0");
xmlHTTP.open("GET","http://myserver/save.asp", false);
xmlHTTP.send(xmlDoc)

The following code belongs on the server.

<% xmlDoc.load(Request); %>
