HTTP headers lookup

What is an HTTP Headers Lookup?

An HTTP Headers Lookup is a diagnostic tool used to retrieve and display the HTTP headers exchanged between a client (usually a browser) and a server. These headers contain important metadata about the communication, including content type, server software, cache policies, and security directives. Understanding these headers is crucial for web developers, SEO specialists, and cybersecurity professionals.

How Does the HTTP Headers Lookup Tool Work?

To use the HTTP Headers Lookup tool, simply enter the URL of the web page you want to inspect. The tool sends a HEAD or GET request to the specified URL and retrieves the HTTP headers from the server response. These headers are then displayed in a readable format for further analysis.

Benefits of Using an HTTP Headers Lookup Tool

• Debugging: Identify issues with web requests and responses by analysing header data.
• Analysis: Gain insights into server configurations, redirection logic, and caching behaviour.
• Simplicity: Requires only a URL input to provide a comprehensive header breakdown.
