Am trying to pass Ref(f)erer via 301 redirect from HTTPS domainA to HTTPS domainB using cloudflare workers.
1) User enters https://domainA.com in a browsers address field, such request headers are send to server:
This request is then handled by such Cloudflare worker:
<...>
return new Response("Will Redirect", {
status: 302,
statusText: 'Found',
headers: {
Location: "https://domainB.com",
"Referrer-Policy": "unsafe-url"
}
})
<...>
This code generates such HTTP response:
It'd seem "so far so good" - Referrer policy header is set and is appearing, but prior to Request/Reponse headers Chrome shows 'General' piece of information on the same request:
As I understand, ^ is a quick summary of request/response combination. Where does this Referrer Policy : no-referrer-when-downgrade line get there? Is it Chrome's default Request parameter or Chrome adds it on response by default? Or maybe these are some Cloudflare defaults? I guess that is one of the potential reasons why I am unable to pass Referrer.
Then the 302 redirect loads the domainB and this request is handled by second worker:
<...>
let refr = request.headers.get('Referer')
let resp = new Response(`Testing referer: ${refr}`)
resp.headers.set('Referrer-Policy', 'unsafe-url')
return resp
<...>
The second request/response is as follows:
But the response from domainB looks as follows:
Though i'm expecting to see Testinf referrer: domainA.com . How would I achieve this?
Thanks!
