Depending on browser policy and request conditions, the HTTP <code>Referer</code> header can identify the source origin or include a fuller source address. If that address contains sensitive path structure or query data, navigation metadata becomes an unintended disclosure channel.</p> <p>Referrer Policy gives a document, response, or individual element control over how much source address information accompanies eligible requests. It does not encrypt traffic, authenticate destinations, or prevent navigation. Its purpose is narrower: constrain the referrer information exposed when the browser makes requests.</p>
