Good stuff, thanks!

One suggestion: I see in request, preflight request, and preflight response, you've organized the headers into required and optional, while the response headers are not organized as such. Would be nice to show which are required for response headers.

Glad you like it.

Thanks for the suggestion but I think I did. The preflight response node lists all required and optional headers. The same as in the preflight request node. Let me know if I missed something.
