What Are HTTP Headers?
HTTP headers are the core part of the communication between a web browser and a server. They are pieces of information sent with every request and response, containing metadata about the transaction.
Response headers, which this tool shows you, tell your browser important details like the content type (e.g., HTML, image), caching policies, server software, cookies, and redirect locations. Analyzing these headers is crucial for debugging, performance optimization, and SEO.

Important Headers Explained
Status Code
An HTTP status code is a three-digit number that a web server sends back to your browser in response to a request. These codes tell the browser how the request went. They are crucial for understanding the health and accessibility of a website.
200 OK
This is the ideal status code. It means the server successfully processed the request, and the requested page was found and sent to the browser.
301 Moved Permanently
This code indicates that the requested URL has been permanently moved to a new location. The new URL is provided in the response, and this is the best type of redirect for SEO.
404 Not Found
This is a client-side error indicating that the server could not find the requested page. It often means you've clicked on a broken or dead link.
500 Internal Server Error
This is a server-side error, meaning something went wrong on the website's server. It's an issue with the website itself, not your connection.
Cache-Control
This header tells the browser how long it can cache (store) a copy of the page. A well-configured cache policy is vital for website speed and performance.
Location
When the status code is a 3xx redirect (like 301 or 302), this header provides the new URL that the browser should go to.
Practical Use Cases
SEO Auditing
Verify 301/302 redirects, check `Cache-Control` policies, and ensure server configurations are SEO-friendly.
Developer Debugging
Troubleshoot API responses, inspect `Content-Type` headers, and debug cookie (`Set-Cookie`) issues.
Security Analysis
Check for security headers like CSP, HSTS, and X-Frame-Options to harden your website.

Is this service really free?
Yes, absolutely. Our HTTP Headers Viewer is 100% free to use. There are no usage limits, no hidden fees, and no registration required to use the tool.
Is my search private and anonymous?
Yes. When you check a URL, the request is made from our secure servers, not from your computer. This means the target website will see our server's IP address, not yours, keeping your check private.
Why can't I get headers for a specific website?
Some websites may have security measures (like a Web Application Firewall or WAF) that block requests from automated tools or known server IP ranges. If the site is down or configured to block such requests, our tool may not be able to retrieve the headers.
