What are HTTP Headers?

HTTP headers are metadata exchanged between a client and a server during a web request. They convey important information about the response such as content type, caching behavior, redirection, security policies, and more.

This tool performs a HEAD request to the given URL and displays all response headers, optionally following redirects to the final destination.

Common HTTP Headers Explained

Status: HTTP response code (e.g., 200, 301, 404)
Content-Type: Media type of the response (e.g., HTML, JSON)
Location: Used in redirects to specify the new destination
Cache-Control: Caching instructions for clients and proxies
Server: Web server software identifier
Set-Cookie: Sends a cookie to the client
Strict-Transport-Security: Enforces secure HTTPS connections

Why Inspect HTTP Headers?

🛡️ Security: Detect missing or unsafe headers
⚡ Performance: Check caching behavior
🔀 Redirects: Debug redirection logic
🌐 Debugging: Validate API, CDN, or proxy responses

What Is a HEAD Request?

A HEAD request is an HTTP method that retrieves only the response headers, without downloading the full content body. It's commonly used for:

🔍 Verifying resource availability
⚠️ Inspecting redirect behavior
📏 Checking content type and size metadata

Our tool uses HEAD requests for fast, bandwidth-efficient analysis.
