Local $bSuccess = False

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

$oHttp = ObjCreate("Chilkat.Http")

; The FollowRedirects property controls whether redirects
; are automatically followed.  The default behavior is to
; automatically follow redirects.

; Explicitly set FollowRedirects so that redirects are NOT automatically taken:
$oHttp.FollowRedirects = False

$oResp = ObjCreate("Chilkat.HttpResponse")
$bSuccess = $oHttp.HttpNoBody("GET","http://yandex.ru/",$oResp)
If ($bSuccess = False) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

Local $iStatus = $oResp.StatusCode
ConsoleWrite("HTTP Response Status: " & $iStatus & @CRLF)

; The FinalRedirectUrl property will contain the redirect URL
; If FollowRedirects was equal to True, then all of the 
; intermediate redirects (if any) would be followed until
; there were no more redirects.  However, because 
; FollowRedirects is not True, FinalRedirectUrl contains
; the next redirect URL.

Local $iLoopCount = 0

While ($iStatus = 302)

    ConsoleWrite("Redirect URL: " & $oHttp.FinalRedirectUrl & @CRLF)

Local $sNextUrl = $oHttp.FinalRedirectUrl
    $bSuccess = $oHttp.HttpNoBody("GET",$sNextUrl,$oResp)
    If ($bSuccess = False) Then
        ConsoleWrite($oHttp.LastErrorText & @CRLF)
        Exit
    EndIf

    $iStatus = $oResp.StatusCode
    ConsoleWrite("HTTP Response Status: " & $iStatus & @CRLF)

    ; For safety, prevent infinite loops by
    ; keeping a loopCount and only allows following a max 
    ; of 10 redirects:
    $iLoopCount = $iLoopCount + 1
    If ($iLoopCount > 10) Then
        ConsoleWrite("Too many redirects." & @CRLF)
        Exit
    EndIf
