如果在< iframe>中点击链接，HTTP Referer是什么？ [英] What is the HTTP Referer if the link is clicked in an <iframe>?
问题描述
假设我有一个网页位于 http://www.website.com ，并带有< iframe> ; 在里面。像这样：
< html>
< head> ...< / head>
< body>
...
< iframe src =http://www.washington.edu>
...
< / body>
< / html>
现在假设有人前往www.website.com并单击iframe中的链接（此链接位于www.washington.edu网站）。
我的问题是这种情况下的HTTP Referer是什么？
它是 http://www.website.com （托管iframe的页面）还是http://www.washington.edu （链接被点击的页面）？
它取决于浏览器。
Firefox和Safari会将引用链接报告为，而某些版本的Internet Explorer将显示 http://www.washington.edu 作为推荐人。

Suppose I have a webpage located at http://www.website.com with an <iframe> in it. Like this:
<html>
<head>...</head>
<body>
...
<iframe src="http://www.washington.edu">
...
</body>
</html>
Now suppose someone goes to www.website.com and clicks a link in the iframe itself (this link is located on www.washington.edu website).
My question is what is the HTTP Referer in this case?
Is it http://www.website.com (the page hosting iframe) or is it http://www.washington.edu (the page in which the link was clicked)?
It depends on the browser.
Firefox and Safari will report the referrer as http://www.website.com while some versions of Internet Explorer will show http://www.washington.edu as the referrer.
UPDATE 2015-04: Testing latest versions of above mentioned, all of them would return http://www.washington.edu
