Behind every webpage load, a silent conversation happens between your browser and the web server using the Hypertext Transfer Protocol (HTTP). Part of this conversation involves sending HTTP Headers – pieces of metadata that provide critical instructions and information about the requested resource and the server's response. While usually invisible, these headers dictate caching behavior, content types, security policies, redirects, and much more.

Our HTTP Header Viewer tool lets you peek behind the curtain. It fetches and displays the raw response headers sent by the server for any given URL, providing invaluable insights for troubleshooting and analysis.

Why Examine HTTP Headers?

Inspecting response headers is crucial for:

• Web Developers: Debugging issues with caching (Cache-Control, Expires, Pragma), understanding redirects (Location, Status Codes: 301, 302), verifying content types (Content-Type), and checking server responses (Status Codes: 200, 404, 5xx).
• SEO Professionals: Confirming correct redirect implementation (permanent 301 vs temporary 302), checking for X-Robots-Tag directives that affect crawling/indexing, and verifying Link headers for canonicals or hreflang.
• System Administrators: Verifying server configurations, checking web server software (Server header), and ensuring security headers (Content-Security-Policy, Strict-Transport-Security, etc.) are correctly implemented.
• Curious Users: Learning more about how websites operate under the hood.

How to Use This HTTP Header Tool:

1. Enter the complete URL (make sure to include http:// or https://) of the webpage or resource you want to inspect.
2. Click the "Parse Headers" or "Check Headers" button.
3. The tool will then make a request to that URL from our server and display the list of HTTP response headers exactly as received. This typically includes the HTTP Status Code (e.g., 200 OK, 301 Moved Permanently) and various Header-Name: Value pairs.
