HTML HTTPS和HTTP请求间不会传递referrer
阅读(5784)在一个HTTPS页面,如果有到HTTP页面的请求,是不会带上referer信息的。
反之,HTTP页面发送的HTTPS请求,也不会带有referer信息。
如果都是HTTPS协议,则会正常带有。
浏览器遵循的是HTTP1.1 的 RTC规范 :
Clients SHOULD NOT include a Referer header field in a (non-secure) HTTP request if the referring page was transferred with a secure protocol.
