Cloudflare Tunnel buffers HTTP responses

[libmartinito]

Describe the bug It seems that the HTTP responses when using a cloudflare tunnel is buffered.

If it's an issue with Cloudflare Tunnel:

4. Tunnel ID : a327cce8-181d-4a07-8d11-fb3109b2fb6b
5. cloudflared config: Nothing special, just the hostname and the service it points to

Expected behavior It is expected that logs will be streamed real time like this (this was using ngrok):

But, currently it behaves like this:

Environment and versions

• OS: MacOS
• Architecture: ARM
• Version: Sonoma 14.0

If your response has a Content-Type: text/event-stream header the tunnel will not buffer it

This is a problem for my Remix application and unfortunately the workaround provided by @stevehansen does not work as we have to use text/html for the page to render correctly
