Using the HTTP Header Check Tool

This tool is typically used to test the X-Pull configuration of your server, check if hotlink protection is working, or provide you with the full details of the HTTP response header with curl in the background, such as:

• HTTP status codes
• Content-Type
• Vary
• Expires
• Cache-Control
• Content-Encoding
• Access-Control-Allow-Origin

And check if you have HTTP security headers in place, such as:

• content-security-policy
• x-xss-protection
• strict-transport-security
• x-frame-options
• public-key-pins
• x-content-type

What is curl?

curl is an open source command line tool used for transferring data with URL syntax, in this tool's case, HTTP and HTTPS requests.
