谷歌如何知道我？

-1

我用curl請求www.google.com這樣：谷歌如何知道我？

curl -v --url "http://www.google.com"

我發現結果是HTTP/1.1 302 Moved Temporarily到Location: http://www.google.com.eg/。

儘管當我檢查HTTP請求標題時，我找不到任何可以告訴我的事情，例如， accept-lang。

Here's the output of the above `curl` command: 
* About to connect() to www.google.com port 80 (#0)
