If you want to inspect the headers of a response from some endpoint, look no
further than a quick curl command. By including the -I flag, curl will
return just the headers.
For example, if you are developing a web app that is being locally served at
localhost:3000 and you'd like to see what the headers look like for a
particular URL, you might try something like the following command:
$ curl -I localhost:3000/postsh/t Dillon Hafer
