- What's this?
= private

Makes a unique request id available to the action_dispatch.request_id env variable (which is then accessible through ActionDispatch::Request#uuid) and sends the same id to the client via the X-Request-Id header.
The unique request id is either based off the X-Request-Id header in the request, which would typically be generated by a firewall, load balancer, or the web server, or, if this header is not available, a random uuid. If the header is accepted from the outside world, we sanitize it to a max of 255 chars and alphanumeric and dashes only.
The unique request id can be used to trace a request end-to-end and would typically end up being part of log files from multiple pieces of the stack.
