getResponseHeader Method (IXMLHTTPRequest)
Retrieves the value of an HTTP header from the response body.
strValue = oXMLHttpRequest.getResponseHeader(bstrHeader);
Parameters
bstrHeader
A string containing the case-insensitive header name.
Return Value
A string. Contains the resulting header information.
Example
var xmlhttp = new ActiveXObject("MSXML2.XMLHTTP.6.0"); xmlhttp.open("GET", "http://localhost/sample.xml", false); xmlhttp.send(); WScript.Echo(xmlhttp.getResponseHeader("Server"));
Output
Returns the value of the Server field in the HTTP header, which indicates the current version of the Web server running locally. In this case, the value is "Microsoft-IIS/5.1" for Internet Information Services (IIS) version 5.1, which is the version provided if the local computer is running under Microsoft Windows XP.
HRESULT getResponseHeader(BSTR bstrHeader, BSTR* pbstrValue);
Parameters
bstrHeader [in]
A case-insensitive header name.
pbstrValue [out, retval]
The resulting header information.
Return Values
S_OK
The value returned if successful.
Example
HRESULT hr; BSTR bstrValue = NULL; IXMLHttpRequest *pIXMLHttpRequest = NULL; try { // Create XMLHttpRequest object and initialize pIXMLHttpRequest. hr = pIXMLHttpRequest->getResponseHeader(_T("Server"), &bstrValue); if(SUCCEEDED(hr)) { ::MessageBox(NULL, m_bstrValue, _T("Response Header-Server"), MB_OK); ::SysFreeString(bstrValue); bstrValue = NULL; } } catch(...) { if(bstrValue) ::SysFreeString(bstrValue); DisplayErrorToUser(); } // Release pIXMLHttpRequest when finished with it.
The results of this method are valid only after the send method has been successfully completed. The line, xmlhttp.getResponseHeader("Content-Type");, returns the string "text/xml", assuming the server set "text/xml" as the content type. The full list of header variables you can query can be accessed from the getAllResponseHeaders method.
Implemented in: MSXML 3.0 and MSXML 6.0
