I prefer to make the request directly using Inet.au3. Here is a set of scripts heavily based on the work of other forum contributors and mangled by yours truly. I only take credit for the mangling.
This will give you the raw request data instead of a file download.
; untested usage example
#include "HTTP.au3"
Local $aResponse[3]
$aResponse = HTTP_Request('http://google.com', "", "", "", "", "", "")
msgbox(0,"",$aResponse[0])
msgbox(0,"",$aResponse[1])
msgbox(0,"",$aResponse[2])
HTTP.au3
