What Is HTTP Header Checker?

When a server sends back a response to a page request, it includes headers that aren't directly shown by the browser. With the HTTP header checker, we can display the exact headers the target URL sent back, making it easy for you to analyze.

How Can I Use The HTTP Header Checker Tool?

Using our HTTP header check tool is simple. Enter the URL you want to check and either press Enter or click the submit button. Our server will check it for you, usually completing the process in a few seconds. The result headers will be displayed in full — header name on the left, header value on the right.

Advanced settings allow you to check HTTP headers with different User Agents, add custom headers to the request, provide authentication credentials, and decide whether to check the server's SSL certificate.

Why Should I Use The Tool To Check My HTTP Security Headers?

Websites have many security features that protect them from attacks. The HTTP security headers checker tool will examine your site's headers to see if the security features you need are active. For instance, enabling the Content Security Policy header can prevent script injection. This tool is provided for free to help you check your site's security from the page header.

How To Understand HTTP Status Codes

200 OK: The request was successful.
301 Moved Permanently: The URL has been permanently moved to a new location.
302 Found: Similar to 301, but indicates that the redirection is temporary.
403 Forbidden: The server understood the request but refuses to authorize it.
404 Not Found: The server can't find the requested page.
500 Internal Server Error: The server encountered an error and couldn't complete the request.
503 Service Unavailable: The server is temporarily unavailable, often due to maintenance.
