SSR Image Previews

I am using the SSR guide (with SvelteKit) to use Appwrite on both the server and the client.
I do this by also passing the cookie back to the client and creating a separate Client on the client. This enables features like realtime and (supposedly) storage.

The problem is, that when I use the image preview API (storage.getFilePreview) the image won't load because Appwrite returns a 401.
So, the problem is Appwrite doesn't get any authentication. I figured out that this happens because logging in on the client side sets a cookie on the region.cloud.appwrite.io domain, while my own cookie is on my server, so Appwrite won't see it.

Is there a way to make sure Appwrite is able to see any of my authentication cookies?
I would really appreciate the help, because this is a bottleneck which may cause us to stop using Appwrite.

maybe you can try setting 2 cookies in your server code, one for your domain and one for the appwrite domain

It looks this doesn’t work, because the browser doesn’t allow setting a cookie on the region.cloud.appwrite.io domain while the SvelteKit app is on localhost or another domain.

oh right 😅 I think your best chance would be a Custom Domain setup in Appwrite. also check here about Session Clients
