The HTTP Headers Inspector is a vital debugging utility for web developers, system administrators, and security researchers who need to examine the metadata exchanged between a client and a web server. HTTP headers play a crucial role in modern web communication, controlling everything from caching strategies (`Cache-Control`) and security policies (`Content-Security-Policy`, `Strict-Transport-Security`) to content types and server information. When you enter a URL, our tool sends a 'HEAD' or 'GET' request to the specified address through our secure proxy and retrieves the full set of response headers. This allows you to verify that your SSL certificates are active, check if GZIP compression is enabled, or debug CORS (Cross-Origin Resource Sharing) issues that might be breaking your web app. The interface presents the headers in a clean, organized list, making it easy to identify key-value pairs at a glance. Whether you're optimizing website performance, auditing server security, or simply learning how the web works under the hood, this tool provides the transparency and technical detail needed for professional web analysis.
