Setting a region cookie

Mar 8, 2017, 1:38 PM

Post #1 of 4 (330 views)

We’re trying to get a varnish setup running that sets a regional cookie. I’m having some troubles getting it to work, so any advice will be appreciated.

We’re running Drupal 8 and Varnish 4.1.5 with the geoip2 vmod. IP Geolocation is working fine, and our X-GeoIP headers are being set correctly. What I would like to do is have varnish set a "country” cookie when requests to our home page come in. I’ve got it manipulating the req.http.Cookie header, but it does not seem to be actually setting a cookie in the browser. Any suggestions?

You're setting it in the wrong place/way. To set a cookie in the
browser you must set it in the response sent to the browser inside of
say vcl_deliver. There's no variables so if you need to propogate
data from e/g vcl_recv you can set an "internal" header on the
req....see say https://www.fastly.com/blog/vcl-cookie-monster for an
example.

Hi,

Be careful the method in the link given by Michael doesn't work.
To set a cookie, you must use the vmod header.

And in the subroutines *vcl_deliver* you must add sotmehting like this
(just change the name of the cookie and the value)

header.append(resp.http.Set-Cookie,
> "VarnishCache="+resp.http.X-Cache+"path:/");

Because using the set resp.http.Set-Cookie = overwrite all Cookie written
by the backend.

I just implement this method in my website to get Analytics stats of my
Varnish

So by copying the cloudflare/google analytics cookies for example to a
custom header before stripping them for a possible cache hit, we can later
add it back to the client response cookies? Is it even worth bothering for?
I strip all cloudflare/google analytics cookies and haven't had any
complaints yet. Just wondering what the use case might be.
