A GET endpoint to check the status of a specific port on a given resolvable hostname or IPv4 address.

Use me as the host to auto-detect the requester IP address based on the following headers:

• cf-connecting-ip
• do-connecting-ip
• x-real-ip

These headers are typically added by the application ingress router (ie, Nginx) and so does not need to be explicitly provided.

Note: Whilst the results of this endpoints port check are not logged, if a host is explicitly passed, the URL will be logged to STDOUT. For example;

"GET /foo.com/443 HTTP/1.1" 200 OK

If me is provided as the host, requester auto-detection will be used using the above headers. However, the requester will not be logged. For example;

"GET /me/443 HTTP/1.1" 200 OK

Application logs are not forwarded or permanently stored.
