NGINX Lua comments

[MSevey]

Can be a follow up, but does NGINX and lua allow for comments? Because if so we NEED to be adding them so that others can better understand what is happening here.

Reading this with no context makes me think you are setting the same skylink as the v1 and v2 skylink which intuitively doesn't make sense.

Are we overwriting the content type here or we're only setting it if it's not set? If we're overwriting it that might not be great.
