Is there referrer header while using SSL?

问题

Is there referrer header within domain while using SSL?

回答1:

If a website is accessed from a HTTP Secure (HTTPS) connection and a link points to anywhere except another secure location, then the referrer field is not sent.

The upcoming standard HTML5 will support the attribute/value rel = "noreferrer" in order to instruct the user agent not to send a referrer.

So it seems referrer is not within the domain, but within SSL.

回答2:

At least Chrome supports now a Meta Tag which explicitly allows to send the Referrer when going from HTTPS to HTTP. Just include the following line in the header:

<meta name="referrer" content="origin">
