; This example assumes the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.

$oHttp = ObjCreate("Chilkat.Http")

Local $oResp = $oHttp.GetHead("https://www.chilkatsoft.com/hamlet.xml")
If ($oHttp.LastMethodSuccess = False) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

; Examine the response header.
ConsoleWrite($oResp.Header & @CRLF)

; Here is a sample response header:

; 	Content-Length: 279658
; 	Content-Type: text/xml
; 	Last-Modified: Thu, 12 May 2016 15:14:08 GMT
; 	Accept-Ranges: bytes
; 	ETag: "c1cd8bee60acd11:0"
; 	Server: Microsoft-IIS/8.5
; 	X-Powered-By: ASP.NET
; 	X-Powered-By-Plesk: PleskWin
; 	Date: Thu, 25 Jul 2019 16:40:54 GMT

; Get the Last-Modified header.
Local $sLastModStr = $oResp.GetHeaderField("Last-Modified")
; If the header exists...
If ($oResp.LastMethodSuccess = True) Then
    ; Parse the RFC822 format date/time string
    $oCkdt = ObjCreate("Chilkat.CkDateTime")
    $oCkdt.SetFromRfc822($sLastModStr)

    ; If we want to access individual date/time parts (in the local timezone)
Local $oDt = $oCkdt.GetDtObj(True)
    ConsoleWrite("day/month/year = " & $oDt.Day & "/" & $oDt.Month & "/" & $oDt.Year & @CRLF)
