I have an authentification mutation that currently returns a JWT token in the response body.
I don't really like that because the browser has nowhere to securely store the token.
I would like instead to set the Cookie header using my framework of choice (ktor).
I understand how I can read Cookies and header before the GraphQL request with.GraphQLContextFactory
but is it possible to set Cookie header after my GraphQL mutation succeeds?
I would have expected this in environment: DataFetchingEnvironmen but no luck.

We've done this in our dropwizard based server by having the mutation put a NewCookie instance into the graphQLContext map and setting it on the response. Something similar should be doable in a ktor based server. https://github.com/trib3/leakycauldron/blob/main/graphql/src/main/kotlin/com/trib3/graphql/resources/GraphQLResource.kt#L154-L158
