I propose that support is added for the [GraphQL over Server-Sent Events Protocol](https://github.com/enisdenjo/graphql-sse/blob/master/PROTOCOL.md), like HotChocolate has. This simplifies authentication, since you can use the same authentication as normal HTTP requests. I haven't looked at the GraphQL-specific parts of it, but SSE it itself technically very simple. Here is a demo: ```f# Get( "/sse-test", RequestDelegate(fun (ctx: HttpContext) -> task { ctx.Response.Headers.Add("Content-Type", "text/event-stream") while not ctx.RequestAborted.IsCancellationRequested do do! ctx.Response.WriteAsync( $"data: {DateTime.Now}" ) do! ctx.Response.WriteAsync("\n\n") do! ctx.Response.Body.FlushAsync() do! Async.Sleep(1000) } ) ) ``` You can test it by simply opening that endpoint in a browser (at least Edge works fine). Related: #460
