javascript - Ability of External Javascript to Determine Referer?

Question

Simple scenario:

1) User is on Page A and clicks a link to Page B. 2) User arrives to Page B. 3) An external (hosted on another domain C) Javascript is called when the user is on Page B in this or similar fashion:

<script src="http://www.domainC.com/script.js" type="text/javascript"></script>

4) Is there any way for script.js to tell that the user came to Page B from Page A?

Thanks!

Answer 1

リモート スクリプトはページ B のコンテキスト内で実行されるため、そのグローバル スコープにアクセスできます。
