According to Scripting Guy ()

SyncMode5 can be set to one of the four possible values :

Every visit to the page 3
Every time you start Internet Explorer 2
Automatically 4
Never 0

I've tried all values, but none of them work. Here is my code :

Code:

Break On
GetPage("http://10.10.10.1/kix/kix64.dll?Login") ?
Sleep 10

Function GetPage($URL)
        Dim $HTML, $IECacheKey, $IECacheVal
        $IECacheKey = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings"
        $IECacheVal = ReadValue($IECacheKey, "SyncMode5")
		$IECacheVal ?
        If $IECacheVal <> 3
            $nul = WriteValue($IECacheKey, "SyncMode5", "3", "REG_DWORD")
        EndIf
        $HTML = CreateObject("microsoft.XMLhttp")
        $HTML.Open("GET", $URL, Not 1)
        $HTML.Send
        If $HTML.Status = 200
                $GetPage = $HTML.ResponseText ;or ResponseBody
        Else
                $GetPage = "HTTP Status Code: " + $HTML.Status + " (" + $HTML.StatusText + ")"
                Exit 1
        EndIf
        $nul = WriteValue($IECacheKey, "SyncMode5", $IECacheVal, "REG_DWORD")
EndFunction
