Hello Rick,

Yes, supposedly I've matched the things you mentioned, 6 cookies, sessionid, referer, params, other headers, but there must be something else. <s>

What do you mean by the browser string? The querystring?

>My guess is that you're not exactly duplicating that header. There could be many things that the server does to discriminate. Maybe it's checking the browser string or a referring Url. Or maybe there's a Cookie that was set earlier that's getting passed through?
