What's the best way to determine, *on the server side*, if a user is viewing a page within a frame v2?

Client side solutions won't work for us given that we heavily rely on RSCs.

User agent contains Warpcast/462?

there currently isn't a blessed way

have considered a special header that any farcaster client hosting a frame should set. it'd be cheap to add so if you'd use it happy to set this up.

I would definitely use this.

We are planning to ship v2 frames to render existing Paragraph publication/post pages, and would love to differentiate which server components to render.

Eg we can update our subscribe button component: "If user is viewing this within a frame, render a FarcasterSubscribe button instead of our regular EmailSubscribe button"

I thought this would be trivial but it's not on web as you can't easily set custom headers when loading an iframe

one option is to use a query parameter, slightly uglier but so far I haven't been able to think of any significant downsides.

let me mull this over for a bit
