These curl recipes show you how to add custom HTTP headers to curl requests. This is done via the -H 'Header: Value' command line argument.
Add a Single Header
curl -H 'Accept-Language: en-US' https://google.com
This recipe uses the -H argument to add Accept-Language: en-US header to a GET request to https://google.com. This header tells Google to serve the English version of the page.
Add Two Headers
curl -H 'Accept-Language: en-US' -H 'Secret-Message: xyzzy' https://google.com
This recipe adds two headers to a GET request to Google. The first header is the same as in the previous recipe and the other one is Secret-Message: xyzzy.
Add an Empty Header
curl -H 'Puppies;' https://google.com
In this recipe, we add an empty header to a curl request. We pass Puppies; (with a semicolon at the end) as an argument to the -H option and curl converts it to an empty header Puppies: with no value.
