So…. What does this mean, exactly?

@bridiver

I don’t understand this. I have ajax calls that return json, aren’t they also susceptible to request forgery?

@NZKoz
Owner

it’s the request content type, not the response content type. i.e. what’s in the client’s Content-Type header.

This is never anything other than the browser_generated_types (see later commit).
