    // so it typically only is sent with requests that actually have bodies. One
    // could imagine that Apollo Client would remove this header when constructing
    // a GET request (which has no body), but we historically have not done that.
    // This means that browsers will preflight all Apollo Client requests (even
    // GET requests). Apollo Server's CSRF prevention feature (introduced in
    // AS3.7) takes advantage of this fact and does not block requests with this
    // header. If you want to drop this header from GET requests, then you should
    // probably replace it with a `apollo-require-preflight` header, or servers
    // with CSRF prevention enabled might block your GET request. See
    // https://www.apollographql.com/docs/apollo-server/security/cors/#preventing-cross-site-request-forgery-csrf
    // for more details.
