open Method (ServerXMLHTTP-IServerXMLHTTPRequest)
Initializes a request and specifies the method, URL, and authentication information for the request.
JScript Syntax
oServerXMLHTTPRequest.open(bstrMethod, bstrUrl, bAsync, bstrUser,
bstrPassword);
Parameters
bstrMethod
The HTTP method used to open the connection, such as PUT or PROPFIND. For ServerXMLHTTP, this parameter is case-sensitive and the method name must be entered in all upper-case letters.
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".
bAsync(optional)
Boolean. Indicator as to whether the call is asynchronous. The default is False (the call does not return immediately).
bstrUser(optional)
The name of the user for authentication.
bstrPassword(optional)
The password for authentication. This parameter is ignored if the user parameter is Null or missing.
Example
The following JScript example creates an XMLHTTP object, and then uses the open method to get a copy of books.xml at the IIS Web server running locally. The code then selects the author and title information for the <book id="bk101"> element to display as output.
<%@language=JScript%>
<%
var srvXmlHttp
srvXmlHttp = Server.CreateObject("Msxml2.ServerXMLHTTP.3.0");
srvXmlHttp.open ("GET", "https://localhost/books.xml", false);
srvXmlHttp.send();
var catalog = srvXmlHttp.responseXML;
var author = catalog.selectSingleNode("//book[@id='bk101']/author");
var title = catalog.selectSingleNode("//book[@id='bk101']/title");
%>
<html>
<body>
<pre><code>
<%Response.Write("<p>BOOK SEARCH RESULTS:</p>");%>
<%Response.Write("Author: " + author.text + "<br>");%>
<%Response.Write("Title: " + title.text + "<br>");%>
</code></pre>
</body>
</html>
