To use Curl to send an HTTP header, you can use the -H or --header option followed by the header you want to send.
Here's a basic format:
curl -H "Header-Name: Header-Value" URL
For instance, if you want to send a User-Agent header to http://example.com, you would use the following command:
curl -H "User-Agent: MyUserAgent" http://example.com
You can also send multiple headers by using the -H option multiple times:
curl -H "Header-Name1: Header-Value1" -H "Header-Name2: Header-Value2" URL
Here's an example with multiple headers:
curl -H "User-Agent: MyUserAgent" -H "Accept-Language: en-US" http://example.com
In this example, the User-Agent header is set to MyUserAgent and the Accept-Language header is set to en-US.
Remember to replace Header-Name with the name of the HTTP header you want to send (like User-Agent or Accept-Language) and Header-Value with the value of the HTTP header (like MyUserAgent or en-US). Also, replace URL with the URL of the website you want to send the HTTP headers to.
Note: The headers are case-insensitive so writing user-agent instead of User-Agent will work the same.
