QueryInfoEx

The QueryInfoEx method Returns information associated with the request, such as content-type, cookies and headers, handling multiple headers with the same name.

Syntax

QueryInfoEx(infoType, indexIn, header)

Parameters

infoType

The type of header required, see table below.

indexIn

The zero based index of the header required,

header

The string value of the header. Note you must initialize this to a variant string before you use this function (in VBScript the assignment value = "" is sufficient).

The zero based index of the next header available. Less than zero if failure or no more headers. Special value of -5 indicates there are no headers of this type at all.

Example

The following requests a URL and outputs the headers:

<% Set OCXHttp = Server.CreateObject("OCXHTTP.OCXHttpCtrl.1") %>

result = OCXHttp.GET("http://www.flicks.com/scripts/debug.asp")
%>
<% If  "" = result Then %>

Succesfully requested file.

<BR>
<%
value = ""
nextIndex = 0	' start value to set off the while loop

' first - are there any cookies?
nextIndex = OCXHttp.QueryInfoEx(HTTP_QUERY_SET_COOKIE, nextIndex, value)
if (-5 = nextIndex) Then
	' -5 is a special code - there are no cookies at all!
	response.Write("There are no cookies on this page")
else
nextIndex = 0	' reset
do while nextIndex >= 0
	cookieNumber = nextIndex + 1
	response.Write("Cookie number " & cookieNumber & " is ")
	nextIndex = OCXHttp.QueryInfoEx(HTTP_QUERY_SET_COOKIE, nextIndex, value)
	response.Write(value & " <BR>" )
loop

End if

%>

<% Else %>

Could not request file because: <%= result %>

<% End If %>
 

Cookie number 1 is KCOOKIE=KCOOKVALUE1; path=/a/ 
Cookie number 2 is ASPSESSIONID=XDBWJSZEKHXNPQJN; path=/scripts
