I'm not very sure of being understanding you, but there is something that sounds strange to me:<br />
<br />
I think you are posting a header to an asp page where you get the http_referer server variable.<br />
<br />
It's quite probable that the value you are posting won't be vailable until after the called page is executed, and so the referer is retrieved before you overwrite it's value.

No, <br />
the problem is solved finally. it has to use WinHttp.WinHttpRequest.5.1<wbr /> object instead.<br />
setting &quot;Referer&quot; header on MSXML2.ServerXMLHttp is of no use, it doesn't appear in the http request.

Active Server Pages (ASP) is Microsoft’s first server-side engine for dynamic web pages. ASP’s support of the Component Object Model (COM) enables it to access and use compiled libraries such as DLLs. It has been superseded by ASP.NET, but will be supported by Internet Information Services (IIS) through at least 2022.
