Curl: Check web server with hostname and IP

A nice way to check if the server is responding for a particular hostname. In this case, we attach the host parameter of the HTTP, and the hostname + port.

If you are sending traffic to IP with a different Host entry, it will not connect to the right service and will serve default-backend.

Try:

curl -H 'Host: aws-dns-name.org' IP_Address

Example:

curl -H 'Host: dashboard.com' ec2-18-207-220-253.compute-1.amazonaws.com:30100

Another option is like this:

curl --resolve "www.example.com:80:127.0.0.1" -i http://www.example.com
